Review on Polar Pro Flex Strap by Vijin Wisniewski

I have used several soft Polar straps in the past and have been quite happy with them but decided to purchase this one as an upgrade. It would get 5 stars as it fits well, is comfortable, the closure is better and seems to work just as well as padded straps, but after about two weeks of wearing a small blister appeared on the rubber. The strap is approximately 2.5 cm from the transmitter latch. It is worn almost every day of the week and rinsed and hung to dry after each use. (I can't figure out how to add a photo.) So, assuming this doesn't get bigger or start giving, it should continue to work and work for some time; I would be upset if it didn't because it would be more expensive than soft straps and I expected it to last longer than previous ones.
