Great customer service. I originally thought they were ignoring me, but I somehow put them on my Blocked email list. Once I corrected that they responded very quickly and escalated my ticket quickly and even set up a Google Meet VTC so they could walk me through all my steps. I have been using my Frontier Monitor for 5 years with 700+ workouts recorded and I have a hard time imagining exercising without it. It shows how many minutes in each zone, HRV and now VO2 Max. I really like the two alarms, which I set for different % of max HR. Definitely best HR monitor on the market, and I have used many.

I have had problems with my monitor, but the support team has been very responsive and has agreed to take back my existing monitor and replace it with a refurbished one.

My initial experience, a couple of years ago with customer support wasn't that great, but boy have they turned things around! They responded to my email really quickly and with really good technical advice. It was first class service. Thank you Poonam!!

I have had my fourth frontier for over a year now and had excellent and proactive customer service from the team. I'd highly recommend this device.

I initially thought that the Frontier X2 wouldn't be able to measure and display what I wanted. I was very wrong! I have only had the device a couple of days and it has met my expectations- and I don't think I've got to the bottom of it yet. I got the device to be aware of health issues (AF) rather than sports related. The quality of the ECG printouts is outstanding. I managed to carry out a 17hr reading (including 8 hours of sleep). The speed of delivery to the UK was as stated i.e. really quick and I had a helpful discussion with one of the helpers after ordering. I look forward to finding out more about the Frontier X2 in the coming days.

My early impressions are really good. This looks like any similar heart rate montior, with a chest band containing electrodes. It's comfortable and easy to wear (you rapidly forget you have it on). The difference is it records a continuous ECG rather than just measuring pulse rate. And it does it remarkably well. I'm a doctor, and I know how difficult it is to get a good quality ECG with a sweaty moving patient. Nonetheless, this system achieves it remarkably well. There is some noise/artefact on extremes of exercise, but so far my experience is nothing but positive.

I'm an amatuer cyclist and spinner and Frontier X user that just switched to X2 and have opted for the Premium Service that includes calculation of V02 Max and VT thresholds. First off, I read the recent negative reviews and I have to say, I've not experienced any problems like those described in the two I read. However, the reason I went ahead and purchased the X2 was because after 2.5y, my X started having charging issues. I communicated with support and we narrowed the problem down to two causes: a charging cable failure or a device battery/cable connection failure. I was offered the same 30% discount (only 5% above the 25% discount available to every new X2 purchaser). OK, I get it .....the X2 is expensive but it as an amazing device. I liked every feature of the Frontier X and after studying what is available in X2, I decided to purchase it. After receiving the new boxed X2, I took out the new charging cable and plugged it into my old X device. Boom, it started charging. However, if I wiggled the charging cord connection, the charging stopped and I got a warning on the display to check the charging cord. I carefully re-plugged it to the device and charging resumed. It's now fully charged. So, I concluded I may have had a charging cord failure (I doubt it becasue I bought a new one - same problem) and a connection failure on the device (most likely). I think there is a design weakness but it's not fatal. I think the choice of USB A device connectors instead of USB C should be re-evaluated with a redesign of the next X device iteration that features USB C charging cable connectors. With respect to Frontier taking responsibility for a design weakness in the device charging cable plug, I'd agree with one of the negative reviews that in the case of proven device failures (not operator errors or charging cord failures), that upon contacting support that a pro-rated credit toward the purchase of a new device starting at 50% of the retail price at the expiration of the 1y warranty period, declining to zero % at some point TBD by Frontier (3y?). This way existing customers whose device fails after a year of service or up to 3y, get a reasonable credit towards purchasing a new device and Frontier can incentivise new customers with the % discounts they are using now. New customers thinking about purchasing the X2 should know this is a high-tech device that allows athletes (or weekend-warriors) to fine tune their training and workouts through buying both the X2 and subscribing to the Premium services. I'd like to see real time display of V02 max and VT Thresholds during a workout but that is not currently available. However, the after the fact data in the subscription premium service allows the user to structure training events armed with the same kind of information pro-trainers use to train amature and professional runners and cyclists. The ECGs are as close to the real thing as you can get with a single lead sensor (medical ECGs have 12 leads). There is no non-medical comparable device as accurate as the Frontier's X and X2. Given single lead limitations, it is still fully capable of medical interpretation and diagnosis by a qualified MD, but Frontier makes it very clear the device alone being interpreted by untrained users cannot be used for medical diagnosis purposes. The Frontier App in conjunction with the website makes it easy to get PDF copies of an ECG that you can forward to a cardiologist for review and interpretation. Overall a great product with great tech support. The device works fine when it's operation is understood and used according to the available manuals and published FAQs. I'd like Frontier to consider and offer a little better warranty as the devices aren't cheap. I'm looking forward to improving my cycling/spinning performance with the V02 Max and VT data I'm getting post exercise that will guide my training.

20250107 UPDATE after sending my considerations to the company, thanks to the interest of Sneha, who forwarded my query to the team, they agreed to replace the non-working device with a new one. I just received the new frontier X2 today and I will try it as soon as possible, thank you so much. All's well that ends well! 20241213 It wasn't a good experience!! Please note that company policy, for their products, is to offer only 1 year warranty!! I purchased the Fourth Frontier X2 at the price of Total: €400.76, on April 23, 2023, so 19 months ago. I've always used it correctly, never in the water for swimming or other water sports (even if it is waterproof). After 2 months from the purchase I started having problems, the device crashed very often and I have to reboot the device continuously, but at the end of November 2024 the device turned off and no longer worked. I got in touch with the customer service and according to them the problem is the hardware; they proposed me a "special offer" dedicated exclusively to me. They offered me a 30% discount, but considering that on their site they offer everyone a 25% discount, this means that the "special discount" for me is an extra 5%. Unbelievable!!! No thanks, I will buy another device that offers more guarantees and above all from more serious companies and with different policies than yours.

Updated review - I was having heart issues so was very interested in the frontier x2 to monitor my heart over extended periods and during exercise. However, my personal experience is that the x2 isn’t fit for purpose. At best it works intermittently, often not at all, and when it does record an ecg, it is basically unintelligible for practical purposes. Its performance is even worse when exercising. I have liaised with the helpdesk a couple of times and reset the device but I’ve come to the conclusion that it can’t do what it says it can do. It is no more than a poorly performing run of the mill hrm at 10x the price. Back to my garmin hrm when I exercise and the Kardia when at home Frontier customer services eventually replaced my device. It’s reading as I would expect now but only 3* due to my experience

They sorted it out so I have adjusted the review.
