COROS 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.

Functionality, accuracy, ease of use.

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.

I normally use a chest strap on my training rides because of its accuracy so I was unsure of this device, but it is a brilliantly designed product that is very comfortable and seems very accurate. You forget that you’re wearing it. Very simple without any buttons.I can’t find any thing to criticise.

Really good and reliable - paired with my Garmin with no issues and always pairs with my watch within seconds when I put it on.Also find it’s very reliable - have been a couple of times where it feels HR is slightly high but generally I feel it’s more accurate than other HRM’s and matches my perceived exertion. Battery life is good (probably charge every couple of weeks) but it charges quickly and no issues there. I really very impressed

Works with Garmin and provides same additional metrics that work with Garmin HRM. Bit inconvenient to start with but you get used to it eventually. Still able run with your phone strap. Doesn't intervene

It doesn’t connect to all Bluetooth devices only certain ones so I can’t use it with my garmin despite using other heart rate monitors before with it. Nothing clear on this when purchasing. I can however use it with swift and it’s not as good as others I’ve used in terms of comfort so overall a big waste of money

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.
