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…
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.

Thank you for your valuable feedback on our device! We appreciate your positive comments regarding its effectiveness for heart health tracking and sports training. Your suggestions for improvement are noted. Flattening out the back of the sensor to prevent the snaps from popping off during exercise is a great idea, and we'll consider it for future iterations. Additionally, providing more detailed information about non-Sinus Rhythm events on the website/app, such as flagging them on the ECG, is a valuable suggestion that we'll take into account for enhancing the user experience. We appreciate your input and will continue working to make our device even better.

BEST experience ever-Frontier X2 purchase <3
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
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.

Fantastic device for peace of mind!
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.

Thank you for sharing your detailed and positive experience with the device! We're delighted to hear that the FourthFrontier device has been fantastic for monitoring your heart health, especially after experiencing a heart attack. It's great to know that you were able to track your heart strain in real time while working on your roof, providing you with peace of mind during the recovery process.
We appreciate your feedback on the convenience and versatility of our product compared to a handheld instrument you previously owned. The quality of the traces and the positive comments received from doctors further emphasize its value. While the software doesn't flag AFIB specifically, the ability to flag anomalies in the rhythm and easily review the recorded sessions allows for a closer examination of events like PAC/PVC occurrences, rapid rate changes, and workout recovery rates.
We understand your desire for more comprehensive printouts and the limitations due to file size considerations. We appreciate your suggestion for printing out session ranges in the same resolution and formatting as the online access, and we'll take it into account for future improvements.
Thank you for recommending our device to your friends. We understand that the price point can be a challenge for some, but we strive to provide a valuable and subscription-free solution for heart monitoring. If you have any further feedback or questions, please don't hesitate to reach out. We're here to assist you.

Better than a smart watch for keeping…
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.

We're delighted to hear that you find our device to be better than a smartwatch for keeping track of your heart health! The detailed graphs, charts, and high-quality EKG provided by our device are designed to offer valuable insights. We understand your gripe with smartwatches requiring both hands to get a short EKG view, whereas our chest-worn device allows for a hands-free EKG recording.
In addition to EKG, the device also provides metrics such as heart rate, breathing rate, and strain, which can be incredibly useful. The ability to set alerts for these metrics eliminates the need to constantly check a watch, providing convenience and peace of mind.
Thank you for your positive feedback on the device's features and capabilities. If you have any further questions or need assistance, please don't hesitate to reach out. We're here to help you monitor your heart health effectively!
