Jawbone Up 2nd Gen dies after a month...

I pre-ordered the Jawbone Up activity tracking band, and was a very happy owner of that band for about a month until it died. It died while I was sleeping, and it never woke up (literally, my alarm didn't go off and I overslept). After going through all the steps to reset the band on Jawbone's site this whole situation seems very similar to what happened to Jawbone's first Up band. Reviewers got their hands on it, ,loved it, and then they started to die. I'm curious if anyone else is having the same issue with their 2nd Gen Up.
