I have a very high mileage Treo that has been used and abused. My Treo will not even stay together anymore it's been so battered. The good news is that the Silicone Skin has given my Treo new life. The skin hold the device together like, well like a skin. I could not be happier that the skin has extended the life of my Treo while I'm waiting for the next big deal in PDAs - Apple's iPhone.
