I like the feel and fit of this headset and the price is definitely right.  Battery life is good and no problems connecting to my KRZR phone.  The only complaint I have is that a few people on the other end of the line have complained to me about hearing alot of echo as if I'm talking in a tunnel.  I have tried other bluetooth headsets though and have had the same complaint.  After reading many reviews I am pretty convinced that is a common problem, however.
