Review on Polar Pro Flex Strap by Steven Thelin

If you have a Polar HRM and like me need a new wristband, this is for you. I have a Polar FT4 with an H1 monitor. My chest strap was worn out after a year of heavy use and I had a lot of slipping and twisting issues. In addition, the electrodes became detached from the strap, which meant that my monitor could no longer read my heart rate during exercise. I went with this new version instead of just replacing mine with the same one, which is great. The little rubber dots you see in the picture really help keep the strap from slipping off during your workout/run and the new clip is a lot better than the old velcro method. My H1 device is perfect for this and reads my heart rate right away.
