At first, it seemed great.  Then moisture started collecting below the screen as I exercised, then blotches started appearing on the screen, growing over an hour or so and I was not able to re-set it or anything.  It became unreadable, then it died.  All this happened within a week.  When I last took it off, I laid it somewhere safe, so I could return it, and now I can't find it.  If I do find it before the return period expires, I'm sending it back.

I've had other Garmin products that have failed, and had to be returned.  Once I had to try three times (from another store).  I enjoying seeing the information that the devices provide, and I really like them.  But... if Garmin is good, it's very, very good.  And if it is bad, it is horrid.
