Had to reach out due to a small glitch with my device and I got a) fast response, b) Accurate instructions that solved my issue right away and c) nice follow up. Good customer service model and mindset.

It turned out that I didn't need the monitor after all since my doctor was supplying. They made my return effortless. Thanks Fourth Frontier.

Excellent device for keeping track of heart health and for sports training. My only suggestions would be to would be to flatten out the back of the sensor so that the snaps would not pop off during exercise, and to make the percentage of non-Sinus Rhythm events give more detail to the user on the website/app. The back of the sensor is not flat, so the snaps can pop off during exercise. And as for the non-Sinus Rhythm events, all you see is a simple pie chart showing the percentage of the time during the workout that you we not in sinus-rhythm. This is helpful, but it would be much better to have these events flagged on the ECG, so you wouldn't have to hunt for them.

I purchased the frontier X2 about 2 years ago, and I was having a tough time financially, they let me return it and got my money back. Then, I bought it again, last year, and have just loved this device. I used it so much the power button eventually popped out. Sent it back recently, and they got me a replacement device with completely covered 2-day fedex shipping! This is the BEST service I've ever experienced. 5 STARS EARNED!!

Great product and great service. I ordered the X2 a few months ago and promptly received my order. The device was easy to setup and use. The data for heart activity was surprisingly detailed and the app and web portal was also easy to use. After a few months I started having a small issue with the device. I contacted the support team and received a prompt response. The customer service group was knowledgeable and pleasant to work with. I provided the requested information about the problem and I received a new device within a few days. I highly recommend the FourthFrontier X2 for anyone that is interested in monitoring their heart health.

I have had the device since for about 6 months now, and it has been a fantastic experience. I purchased right after having a heart attack, and I wanted to monitor heart strain and potential for AFIB in real time. Three weeks later I put a new roof onto an outbuilding and was able to track each bundle of shingles I carried up the ladder on my back and showed no abnormal heart strain. There are alarms you can set on items like rate and strain, and the rate went off regularly, but the strain was stead on. I had purchased a handheld instrument for about the same cost 12 years ago, but the convenience and versatility of this product is night and day compared to that. This brought peace of mind as I went through the recovery process. The quality of the traces is excellent, and I have had a couple of doctors make positive comments on this. Although the software does not flag AFIB, it will flag anomalies in the rhythm, and it is quite easy to page through the 20 second "sessions" which the read is recorded in and see plainly what the flag was about. You can easily identify most of the PAC/PVC events, rapid rate changes and look closely at recovery rates from workouts. I am amazed at the lack of noise even when working with the instrument strapped on. You can see noise when the strap is moved, but otherwise it is quite steady. The algorithm they employ is generally pretty good, but because I generally page through the whole reading session by session I have seen rare occasions where it failed to flag an anomaly or flagged it as poor signal when in fact it was quite clean but was quite abnormal. Still it seems that it is probably >98% accurate in flagging things to look at more closely. The flexibility of being able to share a link with your doctor is great, but the printout to pdg is limited in how much information can be included (I think it is limited to 20-30 minutes) and the quality of the trace is diminished compared to being able to access online directly. I am sure this is related to file size considerations, but it would be great to be able to print out a session range in the resolution and formatting that is used online. All in all I have recommended this to friends, but the price point of around $500 is a challenge for most of us. I love that there is no obligatory subscription or recurring charge associated, though there is a service offered if that is desired.

I had a problem with an update and they gave me a good solution with an option to have a meeting on line. Very grateful.

I had a question about how the device worked and they answered all my concerns. Great group of people and a very good customer service

Better than a smart watch for keeping track of my heart! This devices gives some incredibly detailed graphs and charts including a pretty high quality EKG. My gripe with smart watches is that you have to hold the watch with both hands to get an EKG and that too a short 30 sec view. Since this is worn on the chest it can pick up your EKG hands free. The other metrics such as heart rate, breathing rate, starin are pretty handy too, especially because I can set alerts for them and don't have to keep looking at a watch.

I think it is a really good device and app to increase your awareness of how your body reacts to your physical activity and what to do to improve your fitness. I bought this product because I wanted to keep an eye on my fitness level. I enjoy hiking up mountains but sometimes I feel I get a very fast or irregular heartbeat. I have used in the past a Garmin watch, but unfortunately it only lasts for about five hours and my hikes are usually longer than five hours. This device last for days! I also do other sports and it is interesting to compare results across sports. I really appreciate that it also links with my Garmin watch for checking the activity on the map and how my heartbeat and other information shows. It is really cool that you can compare the information on one graph for the different data that the device captures. It also works for indoor bike training on Tacs. The best thing is the opportunity to have an ECG made in shared with your doctor or whoever else you want to share it with. Sometimes I feel my heart is beating irregularly and you can actually highlight this moment through the device and it will therefore be quicker to find it on the ECG. One thing I particularly like is the fact that the app sends you push notifications suggesting you how to train and at what level so to reach better results. I have been curious enough to use it also at night to check how I am sleeping and that also provides interesting information. Having it positioned around your chest doesn’t bother me at all. An extra points is the service that you can interact with a practitioner who can read your results. I think it is a really good device and app to increase your awareness of how your body reacts to your physical activity and what to do to improve your fitness.
