I have only just received my Fourth Frontier Monitor and am trying to use it properly to ensure I get accurate results.
I had a query and decided to contact Customer Service and was very pleased to get a quick response which is very important to a first time user.
The knowledgeable response to my question, answered by Customer Services agent Poonam, was written in a simple and understanding way and which provided me an easy to understand solution.
Early days in ownership but a very swift and positive interaction which was greatly appreciated.

Great product and great service
Very quick from order to receipt, very easy to get started and it links well with my Garmin (which other sensors have not).
Battery life is great and it is really useful to see the percentage battery level on the display.
I also like the fact that you can email directly to real people and you get quick responses!

Buy one.
I've been using this since, oh, god-knows-when. Sure, it can be temperamental, but once they guide you around how to reboot the device, etc. the data you get from it is a joy. Sure, some of it is algorithm-driven, but overall it provides a far more complete picture of your exercise routine and overall cardiac health when exercising. My only complaint is that I'd like a wrist mounted display of the main parameters (HR, HRV, QTc, body shock, breathing). Surely this is possible? I'd pay for it!

Live ECG streaming from a chest strap is
I have a cardiac conduction abnormality (Rate-Related Left Bundle Branch Block) and my cardiologist suggested getting an over-the-counter device that would allow me to see my ECG in real time, so I could modify my workouts as needed, evaluate whether medication trials were working, etc. All the other devices I looked at required stopping your workout and holding the device in your hands in order to get a 30-second ecg, which was not going to work for me, or they had cumbersome stick-on patches, etc.. The Frontier X2 uses a simple chest-strap mounted device and allows me to monitor my ECG in real time when I mountain bike (phone mounted to my handlebars) or, for activities where I can't mount/view my phone, to review the ECG recording after the workout is complete. My cardiologist was impressed with the clarity of the ECG recording, and I find it very easy to review the ECG recordings after a workout. I do wish that a couple of small details were different (I wish we could edit the training load goals to be specific to our workout plans, and it would be nice if workouts recorded through "ECG streaming" would report zone minutes, as do workouts recorded by choosing "start activity"), but these are small details and overall the product deserves 5 stars. In addition, I had a question about receiving inaccurate data when I run, and customer support was quick and helpful (it seems that some women will need to wear the chest strap above rather than below the breasts for optimal positioning for ECG recording, especially in higher-motion sports such as running). In short, I am extremely satisfied with my Frontier X2.

Great support for workouts that feel 'off'
I have a family history of heart problems, so when my cardiologist (also a data geek) told me about the X2, I was immediately interested. It was comforting to know that when something felt seriously 'off' in a few workouts, I could send my MD the data and he could tell me if there was a problem. In my case, the data suggested overtraining, not a CV issue. That was a huge help in figuring out how to proceed.

Really positive and helpful agent
Really positive and helpful agent. Started on live chat, but he realised I needed more and phoned me. He then went through updating, and several other stages to make sure my X2 was working correctly. Very patient, and stayed on the line throughout. Answered all my questions clearly and satisfactorily. An excellent proactive person to deal with.
