CDC estimates that more than one in four adults age 65 and older falls each year. A medical alert is a way to request help; it does not remove the causes of a fall. The first shopping question is what your parent could use after a problem, including when alone in the bathroom or away from home.

Choose a medical alert device by who answers, connection, voice, wearing and charging. Check fall-detection limits, model-specific water instructions and cancellation terms. Compare GPS and caregiver tools with your parent’s routine.

Start with who answers and how the call gets through

NCOA’s feature guide distinguishes at-home systems with a base and help button from mobile devices with location features. A monitored system connects to a response center. For a device that calls family or other programmed contacts instead, ask who receives the call and what happens if nobody answers. Compare that response arrangement before comparing optional features.

An at-home system may use a landline or cellular service. Cellular models do not necessarily need your parent to have a smartphone or a personal mobile plan: Medical Alert’s Home Cellular model connects through the system’s service. Confirm which network the selected model uses and whether it has adequate signal in the home. A coverage map is a starting point; follow the provider’s actual test instructions after setup.

Check five practical functions

1. Fall detection and wearing position

Ask which accessory or device contains the fall sensor, whether that accessory is included, and how it must be worn. A wrist button may simply activate a base station; the presence of a wristband does not establish wrist-based fall detection. NCOA also describes ambient sensors used indoors, a different category from a wearable. Confirm the exact configuration and its coverage rather than asking only whether the company “has fall detection.”

Automatic detection can send an alert when it detects a fall without a button press. NCOA’s September 2026 comparison warns that devices can miss falls and produce false alarms. Its reviewed providers list fall-detection add-ons from $5 to $11 per month; that is a comparison sample, not a universal price.

Follow the model’s placement instructions, and press the help button when assistance is needed and you can do so. Do not stage a fall to test it.

Comfort affects whether the device stays on your parent. Ask them to try the pendant, wristband or watch and button with their usual clothes. Check whether they can press it with the hand strength and dexterity they have. A preference for a watch is useful information, but it does not prove that one wearing position has better detection accuracy for every model.

2. Two-way voice and actual indoor range

Find out where the microphone and speaker are. On Medical Alert’s Home Cellular system, communication uses the base unit; its wearable button activates the system. The company’s Mobile System has communication in the mobile device.

Those configurations create different voice checks. During an arranged test, ask whether the operator can hear your parent from the bathroom, bedroom and any usual porch or garden location.

A button’s radio range is not the same as the microphone’s pickup range. Medical Alert advertises up to 800 feet for its Home Cellular model, subject to conditions; Medical Guardian’s buyer’s guide advertises different ranges for its home models. Walls, floors and the layout make a home test more useful than selecting the largest advertised number. Ask what the monitoring center does if it receives an alert but cannot hear a reply.

3. Water-use instructions for the exact device

Ask whether the wearable is approved for showering or bathing, and follow its manual. Garmin’s published IPX7 explanation describes temporary immersion up to one meter for up to 30 minutes. That rating alone does not settle suitability for hot bath water, soap or a shower’s spray. Confirm the instructions for the help button, mobile speaker unit and charger separately; one component’s rating does not apply to the entire system.

A company can use “waterproof” and “water-resistant” for different components. Medical Alert’s Mobile System page describes its help buttons and speaker unit separately. Ask for the selected configuration’s written instructions, including drying before charging and any restrictions. Keep mains-powered bases and charging equipment in the locations their instructions permit.

4. Power, battery and charging

At-home equipment still has power requirements. Check the base’s backup battery, the button’s battery replacement arrangements and what happens if power or the communication network fails. Medical Alert specifies up to 30 hours of backup power for its Home Cellular base. That is a model specification, not a guarantee that every outage leaves service available.

Mobile equipment adds a charging routine. Medical Alert lists up to four days for its Mobile System, while Medical Guardian’s guide lists up to one day for its MGMove watch. Actual use can affect battery duration.

Ask how long charging takes, who gets low-battery warnings and what your parent uses while the device charges. Try the charging connection during the return period.

5. The full price and exit terms

NCOA’s September 2026 comparison describes monitoring subscriptions starting around $20 a month and reaching $50 or more, before possible extra charges. Use that as a budgeting guide, then get a written total for the selected device and billing schedule. Separate monitoring, fall detection, app access, equipment, activation, shipping and protection plans.

A low advertised monthly rate may require advance payment. A “no long-term contract” statement does not answer refund or equipment-return questions. Read the trial deadline, when billing stops, return-shipping responsibility, lost-device charges and treatment of unused prepaid months.

GPS and caregiver apps answer different questions

For walks, driving, shopping or visits beyond the base’s range, compare a mobile model. GPS supplies location information; the device also needs its specified connection to send an alert and reach the response service. Ask about the cellular network, regular destinations and how the service identifies someone indoors or when a location reading is uncertain.

A caregiver app may show location, battery status or alert history, but the available functions and fees vary. Ask for a demonstration of the exact app: who can access it, which event triggers a notification, whether location is current or last known, and whether there is a boundary alert. Agree with your parent about access.

Ask whether unwanted calling features can be limited while keeping emergency functions available. Establish who checks notifications and who acts if nobody responds.

For dementia or wandering concerns, the Alzheimer’s Association says location tracking belongs alongside other safety measures. Systems are not completely accurate, can work poorly indoors and do not replace a companion. A watch is not automatically a better choice than a pendant; consider what the person tolerates and keeps wearing. Discuss the device and response plan with the care team.

Optional features deserve their own questions

A reminder is not confirmation that a dose was taken. A displayed health reading is not proof that a monitoring center follows it or makes clinical decisions. Ask about the function rather than treating these features as either essential or useless. A parent may value them, but the emergency response arrangement still needs its own explanation.

Match the system to your parent’s day

Living alone after falls: Discuss automatic detection with the healthcare team, while keeping button access, wearing instructions and false-alarm handling in view. Going out regularly: Test a mobile model at usual destinations and plan charging. Memory difficulties: Include the parent’s preferences, a capable helper and a broader wandering response plan.

Mostly at home on a fixed income: Compare the complete at-home cost and trial terms before adding features. A caregiver far away: Ask whether the response center contacts you, what the app actually reports and who can provide nearby help. Distance alone does not make every app function useful; the agreed response plan matters.

For payment, Original Medicare’s equipment policy excludes telephone alert systems because their emergency communication purpose is not diagnostic or therapeutic. Ask a Medicare Advantage plan or Medicaid program about an exact benefit, eligibility, supplier and approval requirement before ordering. Do not rely on a company’s general insurance statement to establish coverage.

What published testing can tell you

NCOA’s methodology uses more than 60 data points. Its score weights are affordability 30%, features 25%, user experience 25%, customer service 15% and brand reputation 5%. It describes setup, calls, location checks and simulated fall tests. Those scores help compare usability and the tested configurations; they are not a study showing that a feature reduces injuries or improves survival.

NCOA discloses commissions from purchases through its affiliate links. FamilyCareWise has not conducted its own device tests; this guide uses published specifications and research. This page has no affiliate purchase links. Confirm the current selected model and terms directly, because a review may describe a different device or an earlier price.

Five questions to keep beside the quote

1. Which device contains the fall sensor, and how is it worn? Ask what is included, what costs extra and how to handle missed or false alerts.
2. Where are the microphone and speaker? Test button connection and voice separately in the intended locations. Ask what happens when no one can speak or hear.
3. What are the exact water-use and battery instructions? Read them for each component and arrange help with charging or replacement if needed.
4. What connection and response service does this configuration use? Confirm landline, cellular or other requirements, who answers, and the fallback if the connection or contact fails.
5. What will the full service cost, and how does it end? Include app and fall-detection fees, the trial, refunds, return shipping and any specific insurance approval.
