CooSpo Optical Armband Heart Rate Monitor with Bluetooth/ANT+ for Peloton, Endomondo, Strava, Wahoo, Garmin, Zwift

I bought this HRM for mountain biking and to use with a Pelaton stationary when the weather is bad. The device is small, I'd say closer to the size of a woman's sport watch. Its thin and out of the way. It uses an optical sensor which is nice and very accurate. I was originally using a chest strap monitor which is accurate, but relies on electrical sensors and the update rate is slower.I use both Garmin and Lezyne cycling computers and had no problem pairing this device with them. For testing purposes, I have paired it with my phone and able to communicate with both Strava and Wahoo with out any problem.The strap is neoprene and easily replaceable with any other sport strap of your choosing. I actually like the original strap and will use it indefinitely.The only thing I don't like about it is it has a proprietary charging cable. It's USB, but the side that connects to the unit is magnetic with contacts (similar to the idea of an Apple Laptop connector). I have not contacted the seller to ask about purchasing the cable by itself, so I have mine locked away as not to lose it.The directions explain how to use is, but it's basically an On/Off button setup. Blinks blue when you turn on and it starts broadcasting, slow blue when synced and reading your pulse, and red when cycling down to shut off.I have owned several chest HRMs from Coospo and they all worked great. So I feel this unit will also be quite reliable.

I really don't like wearing a chest strap heart rate monitor so have been looking for alternatives. Before buying CooSpo armband HR monitor, I tried another armband HR monitor. It was twice expensive as this one, and not quite accurate IMO. So I'm impressed that this optical HR monitor works GREAT!Pros:1) ANT+ & Bluetooth capabilities: easily pairs with devices and apps. It works with Endomondo on my phone.2) It's SUPER comfortable to wear, I barely notice it during the work out. Couple adjustments might be required before you found the perfect place to wear it. To me, upper arm is the perfect place to put it.3) A button to turn it on and off is really convenience. I also like that it has a LED light to indicate the device status.4) It is pretty small and light weight (about 16g).Cons:1) The strap is a bit slip when my arm sweat is sweaty.So far, I'm very impressed. It's a good device overall, and I will recommend it to my friends and family.

I LOVE THIS HEART RATE MONITOR from CooSpo! It is simple to operate and use, and is extremely accurate at tracking my heart rate, even under very vigorous running.There is a hidden and accessible button to control pairing and operation. One click and you are ready to go! So simple. Charging couldn't be easier, and the battery lifetime is great.Most accurate heart rate monitors must be worn on your chest. I don't like this because I can feel the band squeezing my chest, and it is uncomfortable and distracting to my running. And, watch-based heart rate monitors are too inaccurate for me.This HRM from CooSpo is perfect, both comfortable to wear on my arm, and super accurate due to the soft band holding it tightly to my skin.With the price so low, it is a no brainer for me to try it out. I'm glad I did--I couldn't be happier with it!

I love this heart rate monitor. It is super light, easy and waterproof. It syncs 100% no fuss with the Peloton. For a female this monitor is way better than dealing with one that goes under a shirt. Way cheaper than a watch with this feature. Charge lasts quite a bit before recharging. Only thing negative to point out is that the charger is funky. If you lose it, it is not the type of charger you can grab from another device. This one point does not stop me from giving it a 5* but if you are someone who leaves chargers behind you may want to take a pause on this one.

Since my heart attack my chest strap no longer works unless I am very sweaty and my smart watch is not reliable. This unit on my upper arm has been reliable and heart rate matched a stick on monitor used by cardiologist. comparing my smart watch and bike computer I found that a glitch in transmission was a smart watch issue. The armband had continued to send correct information but the watch shifted to wrist sensor for a few seconds for some reason.Tracking heart rate is important to me and the arm band has proven the most useful and reliable for me.

Hi... I actually had to return this watch because I mistakenly thought it wasn't working with my app. When I did, Coospoo responded to make sure there wasn't an issue with the product and if there was anything they could do to help. I thought that was pretty cool! Now I realize it wasn't the watch but the app so I wish I'd kept it so I could see how it continued to work. It is a really nice style and fit.

I bought this to replace a Garmin chest strap HRM that stopped working. I only use it for indoor training on a spin bike and thought the armband would be more convenient, and it is. It works well, however I could not give it a 5 star because it's not as accurate as the chest strap version. When I do interval training, it seems to be lagging at least 30 seconds to register the increases and decreases in heart rate, and I am doing 30 second or 60 second intervals, so that is frustrating. I contacted customer service. They responded promptly and were very open about the armband not being as accurate as the chest HRMs; it uses different technology to sense the heartbeat because of the placement on the body. They sent me a chest version which works flawlessly. If you are doing interval training get the chest strap version, which is actually cheaper: https://www.amazon.com/CooSpo-Fitness-Tracker-Waterproof-Bluetooth/dp/B07BS6B4PDNOTE: Their customer service is excellent.

Even works on my calf/ankle, paired with Endomondo instantly.. I mean the instant I hit search it was in the list asking if I wanted this device. 😳HR is within 1-2 beats of my Fitbit. Even on my leg.The band is comfy, and there were two in the box.So far my Day 0 review is great. I’ll update it weekly till it fails.
