Great Product Lasts a Long Time.
Old school wrapped around the chest, but I replaced the one I've had after almost 19 years. The battery finally gave out. I'm sticking with this model for my treadmill. Now, if I'd only use the treadmill.

As good as it gets
I have used Polar heart rate systems for years. They are rugged and accurate.

Not so easy to find nowadays, but glad to have tracked this one down.
I needed this for an older Tacx trainer, AFAIK no others will work...

Battery not replaceable
It works as expected but the fact that the battery cannot be replaced is a negative.

Didn't get what I ordered.
I was supposed to get a "T31 coded" transmitter but instead I received a regular "T31" transmitter. It worked for about a week and no longer works.

Doesn't connect to the watch
Doesn't connect to the watch and I can't see my heart rate most of the time.
