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

Easy to set up. Connects to watch smoothly. Comfortable. Gives responsive and reliable heart rate data particularly during intense interval training.

Followed the simple instructions; charged it; opened Wahoo Fitness app; added the 'new device' and all worked great! Then the next time I used it I put it on my arm and the sensor lights (against your skin) flashed frantically, but the slow pulsing led on the side (that shows you it's operating) did not light! After looking on YouTube to see how to reset it, it still did the same..! Then I worked out that it was me not realising how it works and that I hadn't needed to reset it. The Coros is very efficient and does not waste energy sending a Bluetooth signal when there is no registered App open! D'Oh!!!! I have now ridden with it a few times and it seems very reliable, I also compared the reading with my existing chest HR monitor, that reads the heart's electrical signal (or something like that), and the Coros reading is almost identical, so I'm very happy with it.

Great product. Well made and comfortable to wear. Syncs easily with phone and watch. Good value for money.

Excellent product. Very accurate

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 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.

If you are a fan of data and numbers it’s must have. I love it and it’s become routine for me to take it for almost every run. I can’t wear chest hrm as they reduce the way I can breath and heart rate become too high but COROS is a game changer for me. It might feel a bit pricey but keep in mind you will probably start to wear it for every run. Connection is good even with Garmin and battery life is long. Strap is nice but I would make it a bit different as sometimes it’s a bit long time to make it different size. Also in some of the cases strap might irritate your skin when rubbing opposite side. Had it during some runs when I don’t use Vaseline and come back home with a bit of cuts.

The order went thro easily and had a very quick delivery, I've used the coros hrm for over a week now, and it's very comfortable, and is giving me a more accurate reading than just the watch wtist hrm.

Fungerar väldigt bra och syncar lätt med Garmins cykeldatorer. Pulsmonitoreringen har failat/låst sig en gång...startade om min Edge 850 och det bara fungerade. Jag gissar att det lilla problemet kan sägas bero på Garmin.

Le brassard polar peut être utilisé en natation et sans connexion mais il faut à chaque fois l’allumer et l’éteindre. Le Coros s’allume et s’éteint automatiquement. Les mesures sont semblables entre les 2 Pas de VFC avec le Coros Plus agréable à porter au bras Nickel !!!

これで時計に映る自分の心拍に自信を持てるようになった。 トレランレースで２回使ったが、どちらも自分で決めた心拍上限をしっかり守れる。 これが、後半の粘りに効く。

Bought in Jan, broke in Jun. No idea why. Cant find reasonable customer support

Love this device. First, it seems very accurate. I don’t have something considered gold standard for accuracy to compare it to but side by side with my watch, Hume, other old chest strap and max trainer, the number jumps around the least as you’d expect. Two, the Bluetooth just works. Pairs one click with any of my machines or phones. Never fails. Never disconnects. No fuss whatsoever. Three, wearing it. I wear on my upper forearm and forget it’s there. It’s incredibly comfortable and does not move at all, ever. All that in mind I am glad I finally found the product for me. Completely recommend.
