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!

Rated 1 out of 5 by from Figure out your pairing issues polar I really liked the hrm until it decides to just unpair from my Bluetooth and nothing I do works to restore it. My Fitbit watch has never had this problem. You'd think in this day and age technology wouldn't be so disruptive to a product that's already on the market. Exercise in frustration.

Rated 1 out of 5 by from Waste of money It used to sync with polar personal trainer but since the update, that is no longer the case. They only reason I bought this model is because it syncs the personal trainer. Polar just made it obsolete and an utter waste of money.
