The X plus provides truly a medical grade ECG. I am a physician with both atrial and ventricular arrhythmias. The X plus provides a comfortable and accurate way to monitor 24 hour ECGs both during activity and sleep. It is both more convenient and gives a better read than electrode based systems that I have used, which often fall off or cause skin irritation.

I bought this expensive product nearly a year ago. It has never worked for Afib recording in spite of registering the fault with the help desk. I worked with them for a number of months and they refused to either replace or refund. As an update it worked fine on my spn sobot appears not to recognise Afib, in my case anyway. The beat I have acheived is 24% reading buy I accept that it works on a normal health person without arrythmia.

Although the courier (Evri) really severely let down this retailer the customer service was second to none (Poonam). Thank you. 🙏🙏

I purchased a Frontier X2 from Amazon on the understanding that I could use it to monitor arrhythmias, but belatedly discovered a comparison between the X2 and X Plus, which made it clear that only the X Plus could be used for this function and that it was a prescription-only device. The website really doesn't make this clear and it's ridiculous to offer a continuous ECG monitoring device that doesn't include analysis of arrhythmias. So, the X2 has been returned to Amazon.

I've been using the Frontier X ECG device and want to highlight how impressed I am—not just with the technology, but especially with the support team. Their responsiveness and willingness to help has been exceptional. Any time I had questions or needed assistance, they were quick to respond and incredibly helpful. It’s rare to find a company that stands behind their product with such dedicated support. Highly recommend! One tip for new users: avoid wearing exercise clothing that retains static electricity, as it can interfere with ECG signal quality. Stick to natural fibers when possible for the best results. Highly recommend!

I ordered the X2 and extra chest strap 3 weeks ago ..received the strap quickly...still have not received the device itself...no real communication from their 'staff' other than 'ticket closed'. I was hoping for a good experience so as a physician (MD) I could use it and recommend it to patients..but that will NOT be the case..they still owe me over $429..so no device and no refund...BE VERY CAUTIOUS with this firm...they missed out on a lot more sales !! ADDENDUM- I am thankful for the apology and the arrival of the X2..I am pleased with the device and plan to recommend it to my patients who are interested in tracking their heart rhythm data. I especially like the ability to adjust one's activity on the app. Thank you for making things right !!

I had provided a 3 star review earlier difficulty working on a product Demo. My errors WRT to that review were due to use of a New PC and use a smart phone as camera. A bad combination which has been correcte. More importantly I want to speak about my satisfaction X2 Heart Monitor Strap and the advanced software subscription. I bought this device for better details and health safety risk profiling, during self reguladed cardio-pulmonary rehabilitation. I have logged 17 work outs across 18 days with the X2. X2 performs exceptionally well. I wear it properly and assure good skin contact. All device aspects, including charging, Bluetooth use perform extremely well. The advance software subscription, properly ports data sets out and detailed analysis reports back seamlessly & timelessly over normal cell phone bandwidth of 1 to 2 bar cell strength. Since i am primarily working from Pulmonary limitations (as a reason for rehab) the generated metrics for V02 max and V0 bands and also cardiac pulse rate data. The cardiac pace on the interface matchs (to within a beat with APPLE Watch heart rate & the sensors in grips on the high end "Lifefitness" treadmills. The picture developed by fourt frontier and software is very complete. The subscription price is well-worth the investment for the refined analysis it provides. The phone application interface is extremely easy to use, and to annotate remarks. Even the availability to publish a web link to share a good look at work out data, are easily studied by others. It suppliments the excellent more detailed presentation available on the smart phone. In these 18 days of use, I cant think of anything else needed for their package. It is also worth noting that all of the agents who were working to support the X2 Demo, and also a discussion around X+ (soon to be released) bent over backwards to try and help me with my connectivity issue to see their demos and discussions. Kudo's to their group. I feel like, within their organization, I could get support and help if it were ever needed. If you are looking for a comprehensive device to support your understanding of work outs / work loads for cardiac functional safety this its a great solution. The buy-in price for an X2 a year with all elements, is significantly lower in price than any a months sessions from "sports medical office-controlled" cardio-pulmony rehabilitation, or advanced sport coaching engagements. With the advantage that you own your own schedule and selection of activities. The safety net the device provides is priceless. The Premium subscription gives detailed metrics, detailed analysis, the summary guidance gives just the right constructive considerations that should apply to improving one's fitness goals. Well done Forth Frontier !!!! This company and their principals will own this space for years to come, because of the pursuit of advance AI work inside the device, and through their gateway that serves back the processed data.

I am 61 yr old male and have been using HR monitors for few years now and although they give you good data about your activity, it wasn't till I discovered Fourth Frontier X2 that I realised what I was missing out on. I am very particular about getting accurate cardiac data whilst exercising and the X2 tells me all I want to know and gives me peace of mind as I do not over reach my limits. And from my experience the Fourth Frontier support team is always more than willing to help if you have any issues. I would highly recommend this product if you are looking to improve your cardiac capability during workouts without worry.
