Stylish metal skins for the LG Shine

These are made by a company called Mozedesign. It's a metal skin sticker that sticks to the top and bottom of the phone (in the pics are the LG KE970 Shine). The company emphasizes that these are not stickers but actual skins made of metal that protects the phone. They look nice but I wonder how durable they are and is it easy to remove them.source
