I love the device and so appreciate the information. IN fact, I need it. But I find the device too unreliable to use. I run daily and need to have a heart rate monitor. My battery is always dead and even after leaving it charged and plugged in, most of the time, I can’t get it to start. I reboot it and do what I think needs to be done, but it still doesn’t work. Often it cuts out in the middle of my run and is dead. :-( however, the customer service has been repeatedly outstanding

Everything is good but .... No C port for charging

The heart rate monitor is great. It is very accurate for real time heart rate when swimming, cycling and running. I don't know how accurate the ECG / EKG is as I have a heart condition so I don't know if my heart rate is actually irregular as much as the monitor says but I plan to check that out with my EP at my next visit with him. I would like to have the ability to talk to some specialists about my data.

I'm 74 and have diagnosed A-Fib although it is paroxysmal not chronic and TBH I rarely experience it. In fact, intense training sessions on a cycle have apparently eliminated my need for anti-arythmic drugs. P-waves are consistently present regardless of HR , 52 (basline pulse) - 150 BPM (my set max HR). Being able to monitor this post work-out (I don't live stream) is a huge benefit. I do experience quite a bit of R to R variance on EKG. Some of this is actual PVCs that I can see on the rhythm strip. I'm told this is not pathologic; it shows up as "other" in HRV. I've also experienced some recently troubling failure of HR to accelerate on demand - just sits at around 75% max. Its occurrence is also rare but possibly indicates a developing AV block that may require an on-demand pacemaker. (I'll leave that to my cardiologist). The EKG feature has been great in keeping me clued in. I can't share it with my cardiologist because his in-hospital network won't allow it (They're in the process of changing over). I find the recommendations for next workout to be no more than boiler plate - I ignore it. Needs improvement that is relevant to my actual training load. The total workload displays are excellent allowing me to compare my cycling work-outs both on good days and bad. The weekly totals allow me to skip a work-out for recovery or, if I'm feeling it in a good way go ahead and safely press it a bit. There is no question that this is the best, most cardiovascular comprehensive wearable device I've used.

From my initial use of the product, my FrontierX has become more stable, and therefore more useful as an ECG-tracking device. As with most computer-like hardware and software, however, Fourth Frontier continues to suffer from instances of poor communication with customers, which degrades one's confidence in the FrontierX/FrontierX2 product. We can only hope that they will invest more attention to this critical service so as to reach their full potential in the future.

My experience echo's this submission below by Mark Lewis. FF's Support was very good with my initial inquiry when I was experiencing connection issues between the HRM and my Garmin 1030+ (intermittent and loss of signal, HRM freezes, loss of workout data, and under-reporting of HR levels in real time to Garmin). Then after reasonable follow up by their Support Team, communication stopped and I have been unable to reach them. I asked if they would consider a "trade in" to replace my Frontier X with their new X2 (that addresses some of my issues) but no response. See detail below for another user's similar issues. It's difficult to justify a $500 HRM that cannot handle the basic (wahoo, Garmin, etc) HRM functionality. BTW - I (tried to) use the FFX as my HRM for cycling with normal rides of 3-6 hrs in duration. from Mark Lewis "I have had this for a few months now,, and felt the need to edit this. For pure ECG this kit is great, but as a HR monitor to connect to other devices, its simply awful. Its overly complicated compared to rivals, and very often just does not display any HR at all, and ends up having to be reset. During rides its a 3or 5 second average of HR for some reason, which isnt particularly usefull, and once or twice an hour will drop out for no reason. Having compared side by side with wahoo and a garmin (wearing both) it just isnt up to spec on this side for the price. Which is very disappointing, considering this should be the easy bit to get right" ** update as of Sep 2022...Fourth Frontier has addressed the issues I was having...with great response from their customer service group after a few attempts to reach a knowledgeable person relative to the device issues I was having.
