Negative Positive
Title: Good for about a year
Review: This strap came with my M61 Polar monitor. It is very comfortable but sometimes difficult to disconnect. The transmitter began to give erratic readings after about a year. Sometimes, after about 30 minutes of exercise, the readings would settle (it had nothing to do with being wet). I regularly cleaned the strap, but decided to clean all contacts too. No help. I replaced the battery. Still no help. I feel this strap is way too expensive to give only one year of usage!
