How we test personal alarms

We put personal alarms through our rigorous test method to find the most reliable.

Personal alarms are devices worn around the wrist (smartwatch) or neck (pendant) that aim to give people a way to communicate quickly in emergencies. Normally this is via a single button, which then either dials or sends an SMS to a family member or 24-hour monitoring service which can then alert an ambulance. 

Personal alarms can be used for two-way conversation as well. 

Here's how CHOICE tests the self-managed plan for several popular personal alarms. 

Our expert testers

With their 30-plus years' experience in the laboratory, we're proud of our expert testers. They've seen all kinds of gadgets come through the labs and they focus on the basics as well as the finer details so that when it's time to buy, you can be sure your new purchase will work well.

How we choose what we test

Why do we choose one personal alarm over another? There are a number of reasons for this, but our priority is to test what you'll see in the shops or prominently advertised in media, on TV or online. That means that sometimes we might not cover a product that has only sold a few units in Australia.

How do we know what's popular? We check current market figures to see what's selling well. We'll also include models that you've requested – if a lot of members want it, we're going to test it.

When we know what you want, our buyers go out and use member funds to buy the personal alarms from a variety of suppliers, then bring them in as-is. This means we get what you'd get, so we can be sure the results are what you'll find, and not 'tweaked' any way.

How we test personal alarms

Reception and tracking

Our testers undertake several extensive journeys to track each of the devices, testing their mobile network reception, GPS accessibility, and battery life to find which ones perform the best. We test reception in a number of areas, including a shopping centre, a house and a black-spot area.

We make calls to the device (if supported), and send an SOS from the device. We also conduct two longer multiple-stop journeys to see whether the GPS tracking functionality is effective throughout busy areas of suburbia.

Ease of use

A good user manual is essential, and this is the first thing we look at. We also check whether each product has email and telephone support. If the device needs a SIM card inserted, we assess how easy this is to do, however most devices come with the SIM pre-installed.

We assess configuring – and in some cases re-configuring – each device, and score based on how easy this is to do. Where applicable, we also assess the ease of sending an SOS, recharging, using buttons, the shape of the device and whether it's easy to grip and carry. If there are differences in these areas, you might see a range of scores for what appears to be exactly the same product.

Voice call

We call to and from the device to test whether the voice quality is clear and loud enough to hear. Voice calling is only supported by some models, so it doesn't contribute to the overall score.


We assess the ease of use involved in setting up a geofence, and the alarm's response time and accuracy if the wearer leaves the designated area. This includes whether the alarm has present boundaries or if you can create custom ones. Old models we've looked at were tested under a pass/fail methodology.

New models are assessed for their effectiveness, which is why they have a score. These results do not contribute to the overall score as the method has changed over time, and this feature is only supported by some models.

Responsible supplier certification

Products that connect to mobile networks must be compliant with the Australian Communications and Media Authority (ACMA) guidelines. This includes personal alarms. If they're not, they may not be safe to use. We ask suppliers (or their appropriate agents) to provide proof of certification. We also double-check the National Equipment Registration System (NERS) database in the event that the supplier doesn't get back to us.

A personal alarm will get a CHOICE Expert Rating of 0% if the supplier can't provide proof of certification and we can't locate it in the NERS database. We'll continue to publish test results for all products under the "original CHOICE Expert Rating" score in our table. This only factors in performance and doesn't include ACMA certification. We don't recommend buying personal alarms without this certification, however we include the score in our comparison table so you can see how these models perform.

Test criteria explained

CHOICE Expert Rating

The CHOICE Expert Rating is a combination of the reception and tracking performance and ease of use, weighted as follows:

  • reception and tracking (50%)
  • ease of use (50%).

Voice calling and geofencing assessments do not contribute to this rating.

Why we don't recommend personal alarms

Personal alarms are often targeted at individuals with people under their care who may have a reduced capacity for independent living. As one organisation that tests these products, we feel we have a duty to inform you of which products reasonably meet their claims, and which do not. However, we will no longer recommend any personal alarms.

We conduct real-world tests when assessing personal alarms, which are designed to replicate consumer usage during day-to-day life. However, experiences are subjective, and we have received a number of emails from members detailing how their products were faulty or didn't work as advertised. These complaints occurred across a number of brands and models, which we feel points to problems with the personal alarm industry as a whole.

We will continue to test, score and publish these products, so you can make an informed decision if you need to purchase one for yourself or a relative. In addition to listing products that we find to perform appropriately, we'll highlight models you shouldn't buy.

We care about accuracy. See something that's not quite right in this article? Let us know or read more about fact-checking at CHOICE.
