I had a charging issue, reported it to FF and within a day got a very helpful response. Reassuring to know that there is always somebody to help you.

I've been using the Fourth Frontier X2 HRM for a little over 18 months, following some concerning heart behaviour during exercise. Recently I was having problems getting reliable data from the strap on occasion, leaving doubts about whether the problem was me or the strap. Yesterday I took part in a video conference with the support team, including a cardiologist. I'm not sure how long the call lasted - it was a good while - and the team really bent over backwards to sort things out and review my data. I do have an appointment coming up for a heart health review and the cardiologist very kindly prepared an email with selected heart data to send to my own doctor. All in all it was an amazing support experience. If I run into further problems the team is keen to help out again. Brilliant!

The customer support provided by Frontier X2 is truly exceptional. They were incredibly responsive to a technical issue I was experiencing and replaced the device .They handled it with professionalism and efficiency. Highest recommendation.

After my device totally froze, would not startup and would not charge, FF arranged a video chat during which they led me through a series of steps to reset the device. After that it is now charging. I thought it was dead!

Received my Frontier X2 last week, got a chance to test it in four different areas that are of interest to me: Running, rowing, sleeping and breathwork/meditation. Impressed with the wealth & depth of data it provides and the clean representation of it. Besides the app, appreciate having a web dashboard as well for greater visibility into the graphs. Certainly takes heart rate monitoring to the next level! Battery life seems good, wore it for 12+ hrs straight and it was more than 50% at the end. It does stick out a bit so not sure I'd use it for sports that involve chest contact.

I'm not a super serious athlete but have always been a very active person with minimal health issues. Was surprised and discouraged to hear back in January that I have mitral valve prolapse with regurgitation at age 41. Have had cardiac symptoms on and off for years but I suppose I underreacted a little to these. I purchased the Fourth Frontier monitor so I could keep tabs on my fitness and heart strain while I exercised because that has been a regular part of my day, especially since I was diagnosed. My cardiologist was very vague and unhelpful about parameters for safe exercise so I decided to take matters into my own hands a bit. I love so many aspects of the app. It even maps my walks for me without me having to do anything. The heart strain parameter is huge for me. If it starts to tick up, I just lessen the intensity a bit. The ECGs do seem very high quality but I can't recognize much other than PVCs reliably at this point. It felt like a big expense at first but I can say after owning it for a few months, it is a great ally in my health and fitness. I try to listen to my body first but I now feel even more confident as I am receiving real-time feedback from this monitor.

as its giving too many parameters and being Ultra Distance Runner with BP. & Marathon Coach , Mumbai India . so its great tools for me to monitor my Heart and now i can train better and safest way. also i suggest my students and track their progress too.

The technology on this device is spot-on. The data is meaningful for any person who wants to see beyond heart rate numbers. The best/accurate sleep tracker as well. Just note that if your device has a USB as a connector, this will eventually rust. Do your best to keep that sealed, dry and away from any sweat and humidity. I am updating the review to 5 stars given that the device has worked very well. Old review - I have used this device for about 1.5 years every day. I am an athlete and I find this to be a great update from a typical heart rate monitor. I have measured the HRM and compared it to others and it seems to be within 1 beat of the typical Garmin HRM chest strap.  What this device excels is in the ability to capture  high-resolution EKGs data while exercising or sleeping. This can help understand how stress affects your heart.  Sleeping capability is useful to understand recovery.  This is not a small device - it is about 2 x thicker than a typical HRM chest strap, so keep that in mind.  It works for me. The device provides EKG and you will need to become knowledgeable to understand what is "normal" or you'll need to seek someone that does.  This device is not going to give you advice or recommendations on your EKG.  When it finds not-normal activities it flags them, however, that does not mean that is a problem...it just means that it is not 'typical'.  There are books like "Rapid Interpretation of EKG's by Dr. Dubin that can be helpful. However, even so, different types of exercise can lead to "non-normal" EKG so you may need to research specific situations as an individual. I have not confirmed that the EKG is reliable.  While it seems to be true-to-form, I have not benchmark it against a medical grade device.  However, one of this new company devices just received approval as a medical grade device, so it does give me confidence that they have the depth of knowledge for accuracy. Additionally, it has extra measurements that can be useful such as heart strain (millivolts), HRV, and breathing rate.    When recording exercise outside, the app actually shows both Garmin and phone GPS data in its own app.  Not that it is critical, but it is nice to have for a quick view.  It also estimates calories, however, that seems inaccurate - especially when resting.  Its calorie estimates seem repeatable, just not accurate. For outdoor exercise, the calorie count is +10% from Strava (which is also an estimate), thus that seems more credible.  Still, I appreciate the company is trying to provide data and I hope they improve those numbers. The battery life is very generous and will last 24 hours of continuous recording. However it is best to record specific activities so that they can be grouped and compared rather than one long stream.  Charging is very quick as well. The Bluetooth performance is excellent.  It has multiple channels and has been very reliable, something I can't say for other Bluetooth devices. The company customer is responsive.  They do know enough to address the device capabilities. The company is actively addressing bugs with updates to the device firmware, mobile app and website.  Additionally, they do add new features (e.g. calories burned) It is the best HRM for an athlete that I am aware of. Thus I highly recommend it. Positives:   > high-resolution ECG continuous 24 hours and while exercising > Excellent battery life > Excellent charging > HRV > Strain/stress,  heart mV > Multi-Bluetooth channels Negatives: >the device will only record down to 35 beats per minute, so if you are below that...it will show 35 as the lowest BPM. I hope that they can lower this limit to 25 BPM.
