Updated review - I was having heart issues so was very interested in the frontier x2 to monitor my heart over extended periods and during exercise. However, my personal experience is that the x2 isn’t fit for purpose. At best it works intermittently, often not at all, and when it does record an ecg, it is basically unintelligible for practical purposes. Its performance is even worse when exercising. I have liaised with the helpdesk a couple of times and reset the device but I’ve come to the conclusion that it can’t do what it says it can do. It is no more than a poorly performing run of the mill hrm at 10x the price. Back to my garmin hrm when I exercise and the Kardia when at home Frontier customer services eventually replaced my device. It’s reading as I would expect now but only 3* due to my experience

Avoid this company. They potentially have a great product if they could sort out these issues, poor quality materials, bugs in the software and poor customer service. I bought my unit in August 2023 and generally it was ok, it started to go wrong in January 2024. The customer service team refused to acknowledge that there was an issue and kept sending me the same instructions to reboot the unit, which worked for a day or two, but this became tedious. Finally after 5 months of no action from them I managed to get them to agree it was a faulty unit and to replace it. The replacement unit worked fine for 3 months and now it wont charge using their bespoke charging cable. As I am over 12 months from original purchase, even though the replacement is 3 months old they wont replace the cable. They are a very difficult company to deal with if you have an issue, they won’t accept the problem is with their equipment. Update, since this review they have resolved the issue by sending out the replacement cable.

Really great idea and design and simple to use but just not quite there... Connectivity drop outs are constantly a problem with devices or will not sync with other third party apps. Heart rate while running is wildly and regularly off target compared to polar (easy zone 2 runs regularly register 180 BPM periods then drops to 0 and I can't tighten the strap anymore as advised!). Sadly end up returning to using polar straps which is a shame as the extra heart Information is a big selling point. Hopefully they will improve.

What a great device when using on my iPhone in isolation from any other device The big downside, however is be wary as it won’t work /!connect with with Zwift or wahoo via ant+ / Bluetooth which is a huge downside if you are seeking a divine for sport.

I purchased an X1 in November 2021 after a heart scare. At 1st i was impressed but within a few weeks the issues crept in and then the device broke within a year even with light indoor-only use. A replacement X2 was sent out as it was still within warranty however 13 months after getting the replacement (by which point i was using the strap very infrequently due to numerous issues) the same issue happened with the X2 where it pretty much fell apart within the monitor. Customer service have taken 5 months to tell me there is nothing they will do as it's out of warranty now so I'm left with a useless bit of kit which I'm unable to repair or recycle and it's been a complete waste of money. The app works poorly, the device doesn't appear to have a way to switch off so i ended up having to charge it before each use, the data refresh was unacceptable when i 1st got it but has improved with software updates since. Beware the claims of intelligent analysis of your workouts, the feedback is very very basic and gives no real insight in to your fitness or training. Edit: since writing the review here the company reviewed my issue and provided a replacement.

I initially wrote a review giving this a one star. It was reliable in its unreliability and I had difficulties getting through to customer service. Customer services did eventually get in touch and were as helpful as they could be. They sent out a second device, which unfortunately still had issues. Following a software update, these do seem to have been resolved apart from the issue of the app not showing the correct battery level when the device is recording. That said, I'll review how the product works (or not) for me. The marketing seems to aim at both the extreme fitness community (of which I'm not able to comment on the appropriateness of the device), and the heart health community. When I purchased the device I was looking for something that could record ECGs for 24 hours. I liked that it also recorded my breathing and at first glance, it seemed to identify any arrythmias which was important for me. I have now given it a good try. The recording is now reliable and I can download 3 hour episodes of ECG on PDF which is useful. When I took these to the cardiologist he questioned whether there was any arrythmia identification or was it just left up to me to guess what was important. This is where the device falls down. I had a Kardia device which would identify specific arrythmias, but was limited to a 5 minute recording when sat still. This device does seem to do a lot, but why there is no AI interpretation of arrythmias, I don't know. What it picks up as different beats are usually normal ectopics but it seems to miss other issues such as atrial flutter, AF, SVTs etc. I don't want to become an ECG expert to know when something needs bringing to a cardiologist. I expect the device to pick these things up and inform me, which this doesn't. For me, I'm not sure this device gives what I need. Perhaps it should focus on the fitness market alone.

The device doesn't always connect to the app. Secondly the ecg reports can be difficult to understand. Lastly the battery life is quite weak.

There should be more Information on the artefacts, what the mean.
