Good product but sometimes stops working,
Verified Purchase(What is this?)
This review is from: Polar FT7 Women's Heart Rate Monitor and Sports Watch (Sports)
Sometimes the heart monitor goes offline and it is really frustrating mid-workout. I don't know if it is the product but I've tried to use it exactly as specified and the same thing keeps happening. When it is working, it is a very good product.
