Comes with a spare strap which is appreciated. Although the photos show it being used at the top of the forearm or upper arm I wear it facing in to my wrist and it seems to work fine. I’ve given it 4 stars for accuracy and I have nothing to compare it with but I can say it’s never dropped out and has been ridden through all types of weather without hitch. The proprietary USB cable has been accused of being a downside but the connector supplied allows it to be rainproof witHour clumsy rubber toggles, is magnetic, and engages positively. I left it overnight to charge so can’t comment on charging time. It’s been used on every ride since I bought it (I go out every other day averaging around 45mins, I’m not a serious distance rider) and so far clocked up over 10 hours without running low - I think the advertised life of around 20 hours And I’ve no reason to think I wouldn’t get 15 hours + out of this. It connects in moments to my Garmin 130 and is comfortable to wear. The strap Velcro felt a bit flimsy when I first put it on but it’s never come loose and my confidence in it is 100% now. In my opinion it’s very good value for money. It weighs nothing, you forget it is there and works in all weathers. Can’t ask much more than that. Recommended. Review: Great product and price, exceptional customer service - I've always worn a chest strap, but after some extreme chaffing one day I decided to give optical a go. I chose the CooSpo on the basis of good reviews and because it seemed better value for money than some of the better known devices. The product itself is excellent. Because you wear it higher up your arm (just under the elbow) than wrist-based optical devices it appears to give a more accurate and stable reading - certainly similar to my Wahoo and Garmin chest straps. It paired easily with my Garmin Fenix and iPhone. It's more comfortable than the chest strap, although it does have to be worn fairly tight. The battery is quick to charge and lasts a long time - it held out during a 40 mile run anyway. But there is always a concern that, in the event of a problem, the customer service may not be as strong as the more well-known brands. Not in this case. I stupidly left the charger in Spain, so tried to find a replacement when I got back to the UK. Unable to, I contacted the company. Emma replied within a few hours, and after a slight mix-up (Emma looks after .com, I am .co.uk) she arranged with her colleague to send me a replacement free of charge. It arrived a few days later. Will buy their products again. ## Features - COOSPO Heart Rate Monitor Armband: Patented optical sensor technology for highly accurate heart rate monitoring and measurement.

I’ve found this to be comfortable and gives good data, however I’m pretty sure it would be good anywhere on the arm. **Q: I want to monitor my sleep heart rate continuously for 8+ hours. Does it have the capabilities to do this? What mobile app should I use?** A: Hi.. I think in principle it will do it but I am not sure how long the battery will last in both the device and phone. While I imagine you can have the phone on a charger, the charging port for the device is a magnetic connector underneath the device (normally in contact with your skin). I would not recommend to go to sleep with an active cable in contact with you. Although 5 volts only this is not a medically rated power supply and is not safe. The battery on the device should last you 6 hours from full but after that I am not sure ... Hope it helps **Q: Hi. does this product work with 'ride with gps' app? thanks.** A: No idea but it didn't work with my rowing machine and it was supposed to be compatible. Also found it a bit temperamental and didn't always give correct results. Finished up with a chest monitor that is far more accurate and sent it back. **Q: Would this be just as acurate as a chest strap or am i better just getting the chest one, cheaper by £10.00** A: This drops beats as soon as you get in to zone 3. I thought it would be better than a chest strap but it’s not really ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good, lightweight, easy to use. *by M***R on 27 June 2020* Not the cheapest but it does have both Bluetooth and ANT+ connectivity.

The strap can be a bit difficult to get right too tight and it pinches your arm but if too loose it slips down, hence the 4 stars. Produces more accurate data than my built in watch monitor. Just need to find where I last put it now ## Frequently Bought Together - COOSPO Armband Heart Rate Monitor, Bluetooth ANT+ HR Optical Sensor for Sport, Rechargeable Dual Band IP67 HRM, Compatible with Peloton,Wahoo,Polar,Strava,DDP Yoga - COOSPO Bike Computer GPS Wireless, ANT+ Cycling Computer GPS with Bluetooth, Multifunctional ANT+ Bicycle Computer GPS with 2.4 LCD Screen, Bike Speedometer with Auto Backlight IP67 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/86647808-heart-rate-monitors-armband-optical-heart-rate-sensor-bluetooth-4](https://www.desertcart.hk/products/86647808-heart-rate-monitors-armband-optical-heart-rate-sensor-bluetooth-4) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-28*
