AARP Smart Picks
Want to live in your home as long as possible? Medical alert systems — which include devices with a help button that connect users to 24/7 monitoring centers — may be able to help some older adults with this goal.
If users pay for monthly monitoring and press the help button, or if they have automatic fall detection enabled on their device, they can connect with an agent who can answer questions or dispatch help if needed. Because these systems can help in an emergency, they may offer a sense of safety and independence for users as well as peace of mind for caregivers.

When our AARP Smart Picks team worked with older adult testers ages 60 to 65 to find the best medical alert systems, we assessed more than 20 devices on important factors like call response time, operator professionalism and speaker audio quality. Bay Alarm Medical, a family-owned home and personal security company based in California, was our best value pick for its low price, easy setup and quick response times.
In fact, the three Bay Alarm Medical devices we tested all earned high overall scores and had some of the lowest starting costs among the medical alert companies we’ve tested.
Bay Alarm Medical offers four devices:
- SOS Home, an at-home system
- SOS All-In-One 2, a GPS-enabled mobile device
- SOS Micro, a GPS-enabled mobile device
- SOS Smartwatch, a GPS-enabled smartwatch with a touch screen
For this review, we tested all devices except for the SOS Smartwatch, which we are in the process of assessing. Testers gave Bay Alarm Medical devices consistently high scores, particularly praising its at-home device for being user-friendly and having a strong two-way speaker that instills confidence about using it in an emergency. And in our April 2026 survey of 300 people who had purchased a medical alert system for themselves or a loved one in the last three years, 100 percent of Bay Alarm Medical buyers said their device makes it easier for them or their loved one to age in place rather than moving to an assisted living facility.
Read on for our review of three Bay Alarm Medical devices, including details on how they performed in our assessments.
Comparing Bay Alarm Medical models
What to know about Bay Alarm Medical
This company stood out in our testing for their easy device setup, quick response times and strong two-way speakers.
Testers gave Bay Alarm Medical devices high marks for setup and customer experience and said instructions for each tested device were clear and intuitive. Testers also praised the strength and clarity of each device’s two-way speaker. A loud, clear speaker is important for ensuring you can communicate with a monitoring center agent when you need help. Testers gave Bay Alarm Medical devices very good or higher scores for audio clarity.
We also like that this company's live operators responded quickly, often in under 30 seconds, and answered questions helpfully. We consider calls that connect to the monitoring center in under 60 seconds as having a passing score. Overall, Bay Alarm Medical's operator response times and professionalism ranked among the strongest across the more than 20 devices we tested.
Lastly, we especially like the company’s Bella Charms, which are optional charms you can affix to the front of your wearable help button to disguise it as a piece of jewelry. These charms retail for an additional $28 each. A help button that looks like jewelry may help some users feel more comfortable wearing it every day.
- Pros and cons

Pros
Near-perfect setup process
Excellent GPS location accuracy
Strong two-way speaker
Cons
Lanyard for pendant isn’t adjustable
Slightly bulky to wear
Device type: Mobile
GPS tracking: Yes
Waterproof: No, but it is lightly water-resistant and can withstand showers or splashes of water
Key takeaways from our testing
The Bay Alarm Medical SOS Micro is a mobile medical alert system with GPS location tracking that can be worn as a necklace, watch or on a belt clip. In our testing, it was easy to use — right out of the box. Will, a 65-year-old tester, noted the only step he needed to take was to make sure it was charged. "The charger comes packaged with the device, and docking it is intuitive," he said, noting that it didn’t take up much space on his nightstand.
Tester Donna said she’d feel confident relying on the Bay Alarm Medical SOS Micro (shown here) in an emergency, especially when wearing it on her wrist.

Tester Donna said she’d feel confident relying on the Bay Alarm Medical SOS Micro (shown here) in an emergency, especially when wearing it on her wrist.
Since this mobile device has GPS, our lab testers assessed its location-tracking accuracy by traveling to three locations — a suburban grocery store, a hardware store and an airport parking lot — to see whether operators could confirm each location. The SOS Micro passed all three trials, earning a perfect score. For active older adults, having access to assistance outside of the home with the push of a button may help promote independence and offer peace of mind.
This device can be worn three ways: as a bracelet on a strap, as a pendant on a lanyard or on a belt clip. All accessories are included so you can switch between styles. For example, during testing, Will said the bracelet style fit him the best. "The lanyard isn't adjustable and uses a shorter, stiffer cord," he said. "Also, the belt clip feels like it could come loose if you were to fall. I wouldn't want to be reaching for it if I were in an emergency." The device itself doesn’t look worse than others our testers have tried, but they did note that it felt slightly bulky to wear daily.
- Pros and cons

Pros
Exceptionally simple to operate
Loud and clear two-way speaker
Extra-fast response times
Cons
At-home signal range is lower than other systems
Wearable help button looks like a typical medical alert device
Device type: At-home
GPS tracking: No
Waterproof: Yes, wearable help button is waterproof; base unit is not waterproof
Key takeaways from our testing
The Bay Alarm Medical SOS Home is an at-home device that includes a stationary base unit with a help button and a wearable help button that syncs to the base. A helpful feature? The base unit plugs into a wall outlet, so you don’t need to remember to charge it, though it does come with a backup battery in case of a power outage. During our assessment, Will said he felt confident setting up this at-home system on his own. Will said instructions for syncing the button to the base unit were clearly laid out in a welcome packet and easy to follow. "There isn't a lot to think about," he said.
Tester Will said what impressed him most about the Bay Alarm Medical SOS Home device was its strong connection range in his home and clear audio quality.

Tester Will said what impressed him most about the Bay Alarm Medical SOS Home device was its strong connection range in his home and clear audio quality.
If you need help and are within reach of the base unit you can press the large red help button. If wearing the synced pendant, you must press its help button within 1,000 feet of the unit — about the length of three football fields — to initiate a call to the monitoring center. The base has a two-way speaker and the wearable buttons do not, so if you press the wearable help button, you may or may not hear the monitoring center staff speaking to you from the base unit. Whether they can hear you or not, they’ll send help. When Will placed test calls to the monitoring center, he said monitoring center agents were helpful and the base unit’s two-way speaker was strong. "The unit was loud and clear. I had no trouble hearing them up to 15 feet away," he said. "I can hear the unit from almost everywhere in my small home." A powerful two-way speaker is a key feature for this kind of device and can be especially important for older adults with hearing loss.
While the base unit’s speaker was strong in our testing, this device does have a shorter at-home signal range compared to other companies. Signal range refers to the maximum distance from which your wearable buttons will work from the base unit. For example, Medical Guardian and MobileHelp both have at-home devices with a 1,400-foot range. A longer range for an at-home wearable device may make a user feel more confident about pushing the button for help if they’re farther away from the base unit — such as if they’re in their yard or in their driveway but still within range. That said, since this unit has a shorter range compared to others, we recommend it for people who live in smaller homes or apartments. You can add automatic fall detection to this model, but you’ll need to be within range for it to work.
In addition, Will also said the at-home base unit and pendant look like typical, clinical medical alert devices and gave this system just an average score for discretion. If you or your loved one are looking for a less conspicuous device from this company, the mobile Bay Alarm Medical SOS All-in-One 2 received a solid rating for discretion.
- Pros and cons
- Features
Pros
Two color options
Multiple ways to wear the pendant
Battery lasts up to three days
Cons
Setup includes multiple components
May shift uncomfortably when worn as a necklace
Device type: Mobile
GPS tracking: Yes
Waterproof: No, but it is water-resistant and can withstand showers or splashes of water
Key takeaways from our testing
The mobile Bay Alarm Medical SOS All-in-One 2 is a unique medical alert system offering. It has what the company calls a base unit, but it’s actually an on-the-go device that’s slightly larger than most wearables. It can be worn alone and charged every few days, or you can wear the optional synced pendant (it costs $40 extra). But if you use the pendant, it must be within range of the base. This means you’d need to throw the base in your purse, car or pocket and wear the pendant if you were on the go. So what features stood out in testing? First, the base unit and wearable button are available in white or black, which is nice because most devices don’t offer a color selection. Second, the base unit's lanyard and belt clip give users different options for how to wear it. During our evaluation, Donna, a 60-year-old tester, said she liked having the ability to convert the wearable button from a bracelet to a pendant, or wear it on a belt clip. "The different styles give me so much flexibility," she said.
While tester Donna said she liked the versatility of the Bay Alarm Medical SOS All-in-One 2, she said the pendant wasn’t as discreet as she would have liked a necklace to be.

While tester Donna said she liked the versatility of the Bay Alarm Medical SOS All-in-One 2, she said the pendant wasn’t as discreet as she would have liked a necklace to be.
The base unit for this device has a battery that lasts up to 72 hours, which is notable because many on-the-go models need to be charged daily. In addition, the optional help button that syncs to the base is battery-operated and lasts about five years. A mobile device that has a battery life that’s longer than 24 hours can help put users or caregivers at ease knowing that the device should still function even if you forget to charge it for a day.
Because the SOS All-in-One 2 has an optional, wearable help button that syncs to its mobile base unit, Donna noted it was a little difficult to set up. “The user manual was helpful, but it does require a bit more attention since there are multiple components to manage,” she said. She also noted that wearing the base unit as a necklace felt a bit unwieldy. “When it was sitting properly on my chest with the help button facing forward it was easy to access and use,” she said. “But with more active movement like walking, it would shift or flip slightly, which caused it to awkwardly hit my chest.” If you’d prefer a smaller mobile device, try the SOS Micro instead.
How we test medical alert systems
To test medical alert systems, we work with testers ages 60 and 65 and ask them to provide unbiased feedback. They test call response times and GPS tracking accuracy, as well as comfort, design, ease of setup and operator professionalism.
Testers also answer questions like: Was this device easy to set up and use? How comfortable is it to wear daily? Could you see yourself using this device every day?
In addition, we perform a series of lab-controlled tests assessing the following criteria, which survey respondents, focus group participants and experts told us were most important:
- Fall detection
- Call connection speed
- Audio clarity
- Operator professionalism
- GPS location tracking

Does Medicare cover Bay Alarm Medical alert systems?
In general, original Medicare — Medicare Parts A and B — does not cover Bay Alarm medical alert systems. These systems do not fall under what is known as durable medical equipment, which includes medical devices like canes and wheelchairs.
Full or partial coverage may be available under some Medicare Advantage plans and Medicaid waivers may offer some degree of coverage. But individual policies vary, so you can check with your plan to confirm your coverage.
Does insurance cover Bay Alarm Medical alert systems?
Most insurance plans do not cover medical alert systems. But some private insurance policies or long-term care insurance plans may pay for medical alert devices. You can check your individual policy to see if you qualify and confirm whether your insurer would require a letter from your health care provider to reimburse you for any costs.
Comparing the cost of Bay Alarm Medical alert systems
The Bay Alarm Medical alert systems that we tested range in lowest starting price from $27.95 to $34.95 per month for monitoring. In our survey, 95 percent of participants who had purchased devices from this company said they were satisfied with the monthly cost.
Note: You may remember that this company also offers a fourth device, a smartwatch, that we have not yet tested. The cost for monitoring starts at $39.95 per month.
The prices in the chart below reflect the lowest monthly subscription costs for the devices in this review. Your total will depend on whether you add fall detection or bundle devices.
How to save money on Bay Alarm Medical alert systems
Some Bay Alarm Medical alert systems may carry a one-time cost for devices in addition to the monthly monitoring cost. But you may be able to save money on a system from this company by using these strategies:
- Pay monitoring fees in advance. Bay Alarm Medical offers free shipping on your device for most plans when you pay for monitoring quarterly and in advance. If you pay monitoring fees annually, you’ll receive not only free device shipping for most plans but also a free month of monitoring. If you’ve paid in advance and then cancel your subscription, you’ll receive a refund for unused months.
- Watch for sales. The company sometimes offers discounts during the year, including around holidays. For instance, it has offered discounts of up to 40 percent for devices during past promotions.
- Use FSA/HSA funds. Many flexible spending accounts (FSAs) or health savings accounts (HSAs) may cover medical alert systems as eligible medical expenses.
- Check with the Department of Veterans Affairs (VA). The VA may provide benefits for medical alert systems for older adults who qualify. The VA recommends talking with your health care provider about the option of a medical alert device to see if you qualify.
Is Bay Alarm Medical right for you?
You have options when it comes to selecting a medical alert system, so you may be wondering how to tell if Bay Alarm Medical could be a good fit for you or a loved one. So if you’re considering this system, you may want to answer the following questions before you decide.
Do you prefer a longer trial period?
If you’re new to the world of medical alert systems, you may not be sure which device would be the best fit for you or your loved one. That’s why trial periods can be helpful. To this point, Daniel Elliot, an occupational therapist at Jukebox Health in New York City, advises older adults and their families to test a device's features as soon as it arrives, including emergency responsiveness and connectivity. "Wear it on a walk, in the car and at the store. You want to know it works in all the places you spend your time," he says.
If you’re considering a device from Bay Alarm Medical, know that this company offers a 15-day trial period from the time it is delivered to your doorstep, so you can test a device and return it within that period if it does not work for you. However, this timeframe is shorter than the 30-day trial period that some other companies offer. So if you or your loved one would prefer more than 15 days to test, this system may not be the best fit.
Are you active outside your home?
If you or a family member is active and independent, and you’re interested in a device from this company, a mobile medical alert device such as the Bay Alarm Medical SOS Micro or All-in-One 2 may be worth considering.
Do you spend most of your time at home?
If so, the Bay Alarm Medical SOS Home may be worth considering.
In general, an at-home system “may be a good fit for an older adult who spends most of their time at home and can consistently wear or access the help button,” says Pola Ham, an occupational therapist and certified aging-in-place specialist (CAPS) at Touro University in New York City.
You may remember that this company’s at-home unit includes a plug-in base as well as a waterproof, wearable button that lasts five years. In addition, during testing, the unit's audio was loud enough to reach most areas of a small apartment when placed in a central location. That said, if you or your loved one would prefer a medical alert system that you can use while on the go, this at-home device would not be the best fit.
Are you a caregiver who would like to monitor a family member?
If so, you may appreciate that the Bay Alarm Medical SOS Micro and SOS All-in-One 2 are mobile systems that pair with the free Bay Alarm Medical companion app. And this app allows caregivers to monitor users’ locations from a distance.
GPS-assisted devices are often helpful for older adults and their loved ones. "Caregivers can use GPS or activity information wisely by checking in when there is a safety concern, a missed routine or a potential wandering risk, while still respecting the person's dignity, autonomy and privacy," Ham says.
Still, some older adults may have concerns about being monitored. And Ham says families should have open conversations about what monitoring would entail. So, if you’re interested in the companion app from Bay Alarm Medical, you may want to discuss which activities you'd want to monitor — and why.
FAQs
Where can you buy Bay Alarm Medical devices?
You can purchase devices from the company through its website, as well as on Amazon. Bay Alarm Medical is primarily a direct-to-consumer medical alert company, meaning it does not have stand-alone brick-and-mortar stores.
Does Bay Alarm Medical offer a free trial period?
Yes, the company offers a free 15-day trial period that begins when you receive your device. It encourages new users to test their device in multiple areas of their home to verify that it works correctly. If you decide you don’t want the system within that 15-day trial period window, you can ship it back to Bay Alarm Medical, who will refund your money minus shipping costs.
Is there a monthly cost for Bay Alarm Medical?
Yes, like many companies that offer medical alert systems, Bay Alarm Medical charges a monthly monitoring fee. This monitoring fee — which ranges from $27.95 to $39.95 a month at the lowest subscription cost, depending on the device — is in addition to the initial equipment fee for some of its devices. Adding automatic fall detection, which is an optional feature, carries an additional monthly fee.
Does Bay Alarm Medical have fall detection?
Yes, Bay Alarm Medical offers fall detection for an additional fee of $10 a month. When this feature is added, if a medical alert device detects a fall, it automatically connects you to a 24/7 staffed monitoring center, which can dispatch emergency services to your location if you need help or are unresponsive.
