Rated 1 out of 5 by from Unreliable! I bought an H7 heart rate monitor along with a M450 to use for cycling. I've been very displeased with the H7. No matter what I try I get bad data during my rides. I've tried wearing it in different location on both the front and back of my chest, and I bought EKG gel to improve conductivity. Despite all my efforts, I keep getting readings heart rate readings that I know aren't accurate. At this point, I'm going to look at other products that actually provide consistently accurate data as the H7 isn't working for me.

Rated 1 out of 5 by from Broken on Android 6.0.1 Worked Great updated phone to latest android 6.0.1, no longer reports HR to phone consistently. RMA'd and issue still persists. Verified works on earlier versions of android. No other bluetooth device I own has an issue. Fix your appPolar!

Rated 1 out of 5 by from Issue with H7/Android 6.0.1 interface Spent more money to purchase a replacement H7 as Polar Cus Svc advised. Still does not maintain interface for HR...starts then fails to display even with new strap/sender. Remounting app on the Android no resolution. Inet discussions reflect issue is out there but apparently there has not been a patch from Polar. Help!

Rated 1 out of 5 by from Won't get any more of my money This is my 3rd and last Polar product. Issue: it stopped syncing. Just like the first and 2nd. I've only had this one for a month. No, I won't contact customer service, no I don't want another one, no I don't even want my money back. This is a lesson for me. I'll find another HRM. Don't waste your money on this garbage.

Rated 5 out of 5 by from Great all around I've had my ft7 since 2014. It still works amazing. I had purchased an H7 heart rate sensor back in 2015 and it lasted a year in a half. That's amazing seeing how I've seen so many reviews saying it only worked for 9 months. I had to buy a new one and I've had it for several weeks now and it works perfect. Never lose connection.

Rated 4 out of 5 by from Used to be great, but now doesn't sync I have had this HRT monitor for ~7yrs now and it has been great until the latest update to the Polar Beat app for iOS broke the sync capabilities with iPhone 5. It still works with my F55 Polar HRT, so I know the rate sensor is on and functioning properly. It also works with a couple of other apps, just not the Polar app. I wouldn't recommend it to anyone until this gets fixed.

Rated 3 out of 5 by from Its nice, but pairing issues. I would not recommend you use this with a bluetooth device. My daughter has one she uses with the Polar watch and it works great, but it loses bluetooth connection to two different phones i have tried it with.

Rated 5 out of 5 by from Excellent! Battery last very very long ... It's works over Bluetooth with my smartphone and with my old Polar watch at the same time!
