Since December 22, I have been consistently training with the device and I'm extremely pleased with the results. The device provides prompt responses to all my queries and the support team is always dedicated, knowledgeable and empathetic. If you want to prioritize your heart health, I highly recommend Fourth Frontier as an excellent place to start.

I have been using the Frontier X since 2021 when I bought it for recording long-time ECGs. The Frontier X is extremely useful for this purpose because it allows to see irregularities in the ECG - which cannot be done with normal fitness watches. Since my first ECG recordings I have reported a couple of issues and I appreciate that this can be done directly in the Frontier X application on my phone. For all raised tickets I received an immediate response and noticed subsequent improvements through several new versions of the firmware (on the device) and software (of the app). I think that this company and their product have gained maturity and I can (and do) recommend them.

My Frontier X2 is such a significant step up in data access from my old basic heart rate monitors that I can't imagine exercising without it. Neither can my cardiologist.

While there are still some software kinks to work out and some needed features, I will still give 5 stars for the level of data the X2 spits out compared to many other wearables. As a user of an Apple Watch Ultra, Oura Ring, Whoop, and Polar HR monitors, I have learned quite a bit about biometrics and wearables and the X2 provides a wealth of real-time information. I like the idea of using breathing rate as an indicator of strain versus solely relying on heart rate as most apps and wearables do. Customer service is very good so far as well. I have received prompt responses to my questions. I look forward to using the X2 to further improve my health and athletic performance.

Outstanding Customer Service My heart rate monitor wasn't charging correctly, contacted Frontier and they had us run thru different troubleshooting and we provided a video of what is happening when we plug it in to recharge. They identified it was an issue and shipped me their latest Frontier monitor with the new magnetic charging cable/system. So much better than the previous charging system. Pavan was great, he was in constant contact with me and always following up, the best customer service. The product is great, I love using it and it monitors my ECG when exercising since I have AFIB so it is crucial for me to have something like this

I've used numerous health devices, but the FourthFrontier chest cardiac monitor truly stands out. Its accuracy and precision are unmatched, giving me real confidence in the data it provides. But what elevates my experience even further is their exceptional customer support. Anytime I had a query or needed guidance, their team showcased impressive technical skills and quickly addressed my concerns. This is not just a device; it's a comprehensive package of advanced technology and outstanding service. I wholeheartedly recommend it to anyone who values top-notch personal health monitoring.

A step or two above the other chest heart monitors on the market. I am a number geek and really love the wealth of information I am getting from this device!!

A very good level of response to my issue which sorted my problem quickly. I really enjoy using the monitor as it gives me comfort when I train that I am not over stretching myself.

Outstanding support. I opened a ticket and had a solution within 4 to 5 hours that corrected the issue. Can't beat that!

Very helpful customer service. Great product. Would highly recommend.
