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

I used this HR arm band when training for an ultra-marathon recently and found it easy to pair with my Garmin watch. Good for the price, but I can't compare it to any other arm bands as I've never had any others! It does the job anyway. It stays in place on my arm and can slip a bit maybe once or twice an hour, but I just push it back up my arm, it doesn't bother me. The band can be adjusted to any length (velcro). The charging cable connection to the magnetic connection port on the arm band is a bit weak so can detach easily, but that would only matter if you were charging it on the go and moving about (e.g. using a battery pack). The HR measurement was accurate when I compared it manually.

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.

I bought this heart rate monitor to use with my Cateye Padrone Smart Plus, I was a bit dubious as not all third party products work with this particular cycle computer, but it Was a very pleasant surprise that it synced up with both the Cateye cycling app, as well as the computer direct. It seems to be accurate as I compared it with my chest monitor which was giving the same readings, so quite good. I did have a slight problem initially with the arm band as I like to wear my monitor around my bicep, but it seemed to be a bit tight at first, but after a few stretches by pulling it out a few times sorted that out. Over all it is a good monitor easy to sync and easy to use.

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.

Simple connection to Zwift, that's what I got it for. Jobs a good un.

Worked fine for a few weeks. Then all of a sudden it wouldn’t transfer data to the watch even though it was connected via Bluetooth. I purchased a 2nd one and same issue again. Really frustrating!!!!!

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.

I needed a reasonably priced heart rate monitor that would work with my Peloton bike. I purchased a second hand 'smart watch' and this was not very user friendly as I had to connect the watch to my phone and the Peloton app on the phone, I was not able to see my heart rate on the Peloton screen whilst riding so it went back! This device connected in seconds to the Peloton bike, I simply switched it on, connected it, strapped it to my forearm and off I went, it couldn't have been easier. It comes with a spare arm strap and a charging cable. I've only used it once so far but I am sure that the battery will last long enough between charges. I thoroughly recommend the heart rate monitor to anyone with a Peloton exercise bike.
