Easy to put on and get started. Keeps detailed records of heartrate while working out. I don't even understand half of it so.this is defiantely geared for those that have some understanding of heartrate and physical fitness!

Comfortable to wear, and very accurate. Battery life is as stated, maybe a bit longer.
Connected via ANT+ to a Karoo 2, paired and has no problem staying paired.
Use the HearTool app to set your maximum heart rate and you're ready to go. Easy configuration.
The colors are easy to remember, and far quicker to look at than small digits.

The only problem I can find is that the device isn't correctly reporting its battery level via ANT+, it shows as fully discharged all the time.

Edit: I posted this review after my unit died. The company saw the review and immediately offered to refund my money. Great customer service. Looking forward to trying another one of their products.

This watch worked perfectly. I used with my Peleton and it seemed accurate vs other sources. All was good then it died and refused to charge. Too bad, I won't be buying again.

I purchased the Coospo heart rate monitor in June and immediately synced it with my Wahoo Bolt. I had lots of previous experience with the agar in chest strap and the Wahoo arm band so I can compare my experience with those products.

The Coospo immediately connected via Bluetooth with no need to attempt it multiple times. Battery time was advertised at 18 hours but I can attest to 10 hours on some longer rides.

From June to late August this heart rate monitor was so dependable I just tended to forget about past challenges with other finicky monitors when the decide suddenly stopped working. I would press the connect button and would just see the red LED flash at me. My guess was either it stopped charging or just wasn't connecting anymore.

I contacted Coospo literally yesterday and after a few emails back and forth the company seemed as baffled as I about why it stopped working. Without any argument, Coospo asked if I would like a refund or a replacement device. I had such good luck with the device initially that I chose a replacement. The folks at Coospo asked me to video the setup and some of the initial uses this time around so they could monitor it. That also gave me some peace of mind.

Sure - I could have rated them lower because the device quit working but the true test of a good product and company is that when something breaks they fix it - outside the 30 warranty period. I am pretty confident the first failure is just a fluke and am willing to match the positive support from Coospo with faith from my end.

I have owned and used this monitor very often over the last year. It has been both reliable and easy to use. In fact, with nearly daily use, I have only had to change out the battery once., which was after 11 months.
