COOSPO Heart Rate Monitors Armband Optical Heart Rate Sensor Bluetooth 4.0 ANT+ Compatible with iFit Polar Strava Wahoo Garmin Peloton

I was looking for a replacement for the standard heart rate monitor that goes round your chest. This is an ideal alternative. Comfortable to wear, it connects quickly, has a good battery life, and provides accurate readings. The straps are well designed and easily removed for washing. Great product.

Works as advertised. Quicker, easier than a chest strap. Not quite as accurate but works for my purpose of tracking during ski erg and indoor cycling sessions

Very accurate - shows the same heart rate as my Fitbit and also the gym equipment ‘2 hand grip’ system. Downloaded ‘Polar Beat’ and it quickly connects. Great for seeing my HR whilst jogging or rowing, etc. PolarBeat keepsa record of your workouts too. Only downside is the on / off button is too sensitive and you can accidentally turn off.

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.

Perfect hr monitor. Works very well with Polar Flow App and Wahoo app. Comfortable and fits snuggly on my biceps or forearms.

I purchased this for my housemate to use as a fun heartrate monitor during horror streams on Twitch. So this review is also partially through experience of an app that it sends the information to.The monitor works fairly well but if I was to give an estimate on the accuracy I'd say it's more around the 60% range after using other tools and witnessing the differences. If you're not looking for specific monitoring but more of a general vibe, which can vary between 15bpm incorrectly in either direction, then this is worth the price. However if you want something accurate this isn't for you.The strap is comfortable and it's also easy to use. The on/off button itself isn't the most obvious but once you get a feel for where it is, you wont have any issues.The battery is a good length for anything you'd use this for too.

Spend a few more pounds on a better product as this is frustrating to use. The strap is awful, velcro to strong to undo and strap has almost zero elasticity so awkward to put on. The device has no memory and if you move away from iphone it loses connection unknowingly and if you remember to check to see if lost connection - you need to again find in bluetooth settings to reconnect which isn't as easy as you think. The app software is useless as cant even find the device as seems to just find wireless devices - yet this is using bluetooth? If I pair with my Bike I lose the connection to iphone - so doesnt support multiple devices. The plus is that it is rechargeable - many devices are still using batteries - but it unkown when you will need to recharge as no indicator.

Not the cheapest but it does have both Bluetooth and ANT+ connectivity. 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.
