COROSHeart 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.

I got this as an alternative to the chest strap. I use a Garmin watch and it was extremely quick and easy to connect it. Having run a race wearing this I found that it was very comfy, to the point I forgot I was still wearing it on my way home.

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.

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.

Just as expected, beautifully packaged and comfortable and accurate to boot!Connects with Garmin devices without any problems. Switches itself on automatically when you put it on and off when you take it off. Charging is quick. The Coros specific charging connector is magnetic which I think is a good thing. Could be £10 cheaper but considering the price of certain heart rate chest straps it’s a bargain.

Good value for money. Easy to use. Easy to connect or pair with my Garmin and Coros watch

Good experience with this. Used for running and cycling. Comfortable and accurate

I think it is fair to expect Coros app to provide you continuous heart rate data during an exercise. That's the most basic expectation to have. And one pays £70 for their product. Its not a small company.If I have to subscribe to Strava and pay a monthly subscription so that it can continuously read the heart rate data from Coros app, it is ridiculous.Adidas app could not even pair.Nike app only shows current heart rate.The band - Yes is was comfortable. But it was not easy to understand how to make it loose or tight.Heart rate data - God knows about accuracy.. Because I could not even get the data over a period.Coros Support - Email based. So not really happy.Price - Considering above factors... overpriced.Result - Being returned.
