Review: Good device - Works as designed. No major major design flaws. Little bit pricey I would say, but it is highly accurate startup company so they're not fully well known in the business. There's not that many people that wear chest straps to be honest. Accuracy of it is good. I bought it thinking I would exercise a lot more but that didn't happen but I used it for a good 3 weeks or so and then I just got lazy easy to set up. Works with a smartphone there was one weird issue with the battery meter on it but doesn't really matter. It'll say it's more charged than it actually probably is. That's the only issue. Other than that all around it's good
Review: Worth the money! - I purchased the Frontier X2 two weeks ago and have been putting it through its paces across all my activities. I love the chest strap so much that I even bought another one for a nurse friend who suffers from PVCs. This device is worth every penny. My only complaint is that I didn’t know this product existed years ago—but I’m glad I finally found it. I suffer from PACs, so being able to track my workouts on my Peloton, outdoor walks and runs, and especially record ECG activity while sleeping has been incredibly valuable. I wear it almost all the time. I honestly can’t believe the company doesn’t double down more on marketing. As a marketing professional, I see huge potential for this to become a household brand. While the price may be out of reach for some, increased volume could eventually allow for a more accessible price point for the masses. I’m also very impressed with both the app and the web dashboard. I was able to share my data with my cardiologist yesterday, and he was genuinely impressed—so much so that he took down the company information. I spoke very highly of the device, and I hope he’ll recommend it to some of his patients. Prior to this, I was using the Kardia 6L, but I strongly prefer this device.

### ⭐⭐⭐⭐⭐ Great Device
*by J***D on December 22, 2025*

Initially, I had some issue authenticating for a day due to technical issues, so the device was essentially a paperweight during setup. That experience was frustrating and highlighted real gaps in their authentication flow and error handling. However, after providing detailed and constructive feedback, I was genuinely surprised by how quickly and thoughtfully the Fourth Frontier team responded. They acknowledged the issue, explained the root cause, and outlined concrete mitigation steps and roadmap improvements. Not many companies take technical feedback this seriously or move this fast, and that responsiveness was refreshing and earned my reconsideration. Now that everything is resolved, I use the Frontier X2 daily. From a technology standpoint, this device is in a completely different category than standard wearables. The level of insight it provides into cardiac performance during high intensity workouts is something I have not seen elsewhere. The ability to capture and export raw ECG data is especially valuable, as it allows me to perform my own deep analysis using custom tools and applications. For anyone serious about performance, physiology, or personal research, that capability alone is priceless. This is a powerful device built for serious users. While the initial onboarding experience needs continued improvement, the underlying technology is excellent, and the team’s willingness to listen and improve gives me confidence in the product’s future.
