Negative Positive
Title: Wears out quickly
Review: After a week of heavy use, this product became stretched out and now slips down my leg when just walking around - let alone exercising. It's now only usable when I'm sleeping or sitting around for long periods (both exactly the times it isn't needed.)It worked fantastically for about 10 hours of heavy exercise and 40 hours of walking-only use, but is now worthless.
