Wrist band is starting to fall off, can I get a second replacement?

Okay so I went tubing last summer, left it on completely ruined it. I called the fitbit company and they replaced it for free. I guess I put a warranty on it. Now the one I have, I haven't gotten it wet, I haven't done anything to break it and one day it just bubbled. I think it's because I take it off when I take a shower and it's in the bathroom with all the steam. My question is can I get a second replacement or not?
