Customer service at Frontier has been top-notch. They are quick to respond, professional, knowledgeable and looking to resolve any issues. I am also very happy with the Frontier X2 HRM. It connects seamlessly to my Garmin 955.

Rubbish product
Rubbish product. Avoid. Sometimes turns on, sometimes doesn't. Takes numerous attempts to reset it.
Sometimes connects to the app, sometimes doesn't.
For the cost of it I'd expect far better.

Not reliable, very poor service owned for 2 years
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.

Not for me
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.

This is an excellent product and provides insightful data on cardiovascular health during exercise. It integrates well with the iPhone and Garmen products. I have been using this for over a year for cycling and running. They redesigned the charging port which is an improvement over an earlier design.

Fourth Frontier is the best invention I…
Fourth Frontier is the best invention I have come across since sliced bread. As an athlete who underwent open heart surgery in 2019, I was thrilled to know about this new heart rate monitor. I have tried all the new wearables available in the market, but the wrist or ring versions didn't work well for me. However, this wearable chest strap is the most accurate among all the ones I have tried, with several unique features that others don't have. The real-time ECG reading while doing sports is a game-changer. Moreover, their customer service is excellent, and they have always been prompt in answering my queries.

Excellent product and good support
I have been utilizing the Frontier X2 for more one year and it is really a great product.
Due to Tachycardia issues, I now feel very confident when I'm doing training activities and even races.
Esay to sync with Fourth Frontier and Garmin apps.
I've had challenges with the firmware last year. Good support team, quick reply, easily accessible, and very helpful.
I recommend it
