Just wanted to let you know that even though Puravida bracelets are advertised to be worn in the "surf" and shower, mine rusted after 2 dives. I know - I should have expected it for a $12 bracelet but they DID say "surf" and I don't know of any fresh water surfing! The good news is that I sent a photo of the bracelet to customer service and they offered to replace it. Like I said - this is silly and not really a diving issue. Just a little PSA. Btw, while in Cozumel I got a good deal on a "real" silver bracelet (.925) at a little shop named Luna's (near the Mega store off the main road in town). Nice folks - ask for Bernice.
