Heart Rate Monitor, Comfort, Easy to wear, Auto-wear Detection, Precise Data, Bluetooth, 38 Hours Battery Life, Compatible with up to 3 Connections, for Run and Bike

Game changer. I've been using chest straps for the last 15 years. Never really any issues other than batteries dying. Gone through Garmins and then maybe 3 wahoo ones. All fine I guess, the Wahoo's only seem to last a couple of years for some reason. Now, pre-setting the strap for these has always been just one of those things I did, either under a tap and embrace the chill when you put it on, or the spit and rub which always had a mildly kinky vibe to it :) Not to mention the more often than not coffee scented strap after a while. Then I finally cave a get this little switcheroo. I wasn't sure how good it would be using the same kind of system that watch based heart rate sensors use (which always seem to lock on to cadence for me). But this thing is solid. Comfy, requires no spit and means i can add a new weird tan line to my arm come summer. But in seriousness, it's accurate, connects to my suunto watch, (i've not used the coros app), is accurate and i honestly forget I'm wearing it. Plus being that it sits on my upper arm and not at the core of my body, it doesn't get anywhere near as sweaty in the heat.

Very happy with this heart rate monitor. Fits well, is accurate and connects easily with my garmin watch. Would recommend

Love mine. Use it on every run. It does its job so well you’ll forget you’ve got it on. It’s so much more accurate than even a high end running watch and much more comfortable than a chest strap. Connects v easily and battery life is amazing.

Excellent piece of kit, works perfcetly and connected so easily

Comfortable, good quality. I like how you can remove and wash the strap. Accuracy is great. Responds to changes in intensity seems slightly slower than chest strap but it’s far more comfortable and marginal loss in this area. Fit is adjustable.

The simplicity and battery life make this the best. It's just as accurate as the Scosche, CooSpo and Polar HRMs I've used (there isn't much between them for me). While it lacks some of the bells and whistles of the others (things I never really used anyway) that this detects when it's being worn and turns itself on/off as needed is great. It "just works". And that wins for me.

Great HR monitor

It finest with my fenix 7x and does what it says in the tin. Only compatible as a Bluetooth sensor to connect to the watch, it doesn't connect direct to the garmin connect app. I wish garmin did a arm HRM
