Overall: I saw the great reviews, bought one of these and it seemed fine, if a bit hot and fiddly to put on. But I couldn't believe it when the strap pinged out during a run. I found somewhere to go and adjust it (had to stop and walk half a mile to public toilets). It happened again, and again - maybe every third run, so I threw it away. Terrible design.
