I got one when my Garmin strap died, and I've been pleased with it for 2-3 years; easy to put on and take off, easy battery change, easy pairing.

And now it's broke. It looks like the snap in the "head" corroded and "welded" to the strap, so when I took it off last night the part of the snap on the unit broke off and came off with the strap. My sweat must be highly corrosive, and I don't see any easy way to fix it. Any suggestions would be welcome!
