I would not suggest the BoxWave treo600 Flexiskin skin. I sent them an e-mail asking if it would allow me to charge through the cradle, they said it would, so I ordered it at $32. When I got it, I noticed the holes weren't the right size for the top volume control, and the IR hole was all messed up, so I asked for a refund, and if they would refund shipping as well, (since they said it would work the way I wanted and it didn't), and they refused to give me a refund on shipping. Check out this thread for the comments and pictures of the case- I was very dissapointed with first the case, and then the service- I've ordered a sena case instead!
