Polar Chest Strap - Spare, Size- M

Very poor customer service. The item was much too small, I didn’t receive a free return label. Not recommended. Only problems. Only stress with the return. No resolution found.....usw.

Product meets my expectations. Thank you very much to the delivery person!

It is a heart rate monitor chest sender band, used with a wristwatch like device which displays the HR during exercise, I use it for spin class.

Polar is a name, a guarantee.
