(posting this review after using it 3-4 times a week for 8 weeks)This is a great HRM. I'm pretty big and have thick arms, but had no problem strapping it to my upper arm. The battery in it lasts a good while; I ride three or four hours a week and charge it every weekend. As far as I can tell I haven't even come close to running it down. The magnetic charging cable is probably the weakest point; not because it doesn't work or anything, but because I'm worried about losing the cable since there's no backup regular USB port. The strap feels well made, is very comfortable and adjustable, and it even comes with a second strap (which I can't comment on because I didn't need to use it).I've had absolutely zero problems with connectivity to either my Android phone or during Strava workouts. I don't have a chest strap to compare it to, but I check the heart rate analysis after every ride and it seems to track my effort accurately—I've never noticed a period where the data drops out or varies wildly. So it may not be accurate down to the exact BPM, but it's definitely good enough for seeing the big picture over a long ride.As mentioned at the top I've been using this for 2 months now, 3 or 4 times a week for logging cycling workouts. It doesn't move around while I'm on the bike. The strap gets a little sweaty, but since it's fabric instead of a rubbery material it doesn't really bother me. Since it doesn't move around it doesn't chafe or anything like that, it just feels a little bit gross and wet when you take it off. But what strap doesn't?

Works great with Strava app, make sure you read how to link to app. I kept trying to get it BT on my phone. While it is BT on phone it does not show in BT list, you have to open Strava app and connect it there.

paired well with my bike. Very easy to use and set up. I have been using it for several months and still haven't had to charge it. Very impressed with the battery life. Easy to wear and comfortable.

I bought this to replace my original Peloton armband monitor. The band is adjustable but not stretchy. Doesn't fit my upper forearm well so I wear it as a wristband. Unfortunately, it requires loosening and tightening the velcro strap every time. Setup was a breeze and it made an instant connection to my Peloton bike. The reeadout on the screen is identical to the Peloton monitor. 3 stars for band; 5 stars for monitor.

Brilliant unit. brought for my daughter to do zone training at rugby. you pair with polar app on your phone and get the polar app to send audible messages through bluetooth earbuds when you go outside your range. you can set zones on your phone. and also listen to spotify etc. polar records all the training info historically too. great buy thanks so much. i have the polar watch that does all this as well but that is mine, and didnt want to fork out for a new polar or gamin. this is pretty accurate in comparison to the actual polar watch and the bang for your buck is insane! perfect for a teen.

This worked ok for two months.. and then it completely stopped responding. Nothing.Got a replacement. The second one lasted slightly longer, but then it broke again. The company says it broke because I left it on the charger too long. If you are like me, and charge your equipment after a workout, and don't give it another thought until you need it again, don't buy this. It won't last more than a couple months. If you have time to worry about the charge time on your workout gear... feel free to roll the dice. To me, this seems like a high burden on the customer, so I won't be buying anything more from this company.Update: After additional communication with the company, I eventually got a refund.

Issues with monitor spazzing out and giving random readings. Straps are small, had to use the large strap to even get it on my forarm, I'm a bodybuilder and this is a constant issue with these devices. Upper arm is laughably impossible. If you're someone with 18+ inch arms this absolutely WILL NOT fit your upper arm, forearm readings are less accurate due to more movement in the ligaments.Frustrating.

The fit on the arm is great. The heart rate seems to be recorded accurate. I paired it easy with my Suunto Race S, which has s terrible heart rate monitor. Great price, for a high end product!
