I've never owned a skin for my phone before, I always wanted one, though. I love that you can have most of your phone protected from scratches without the bulk of a case, and especially with the carbon fibre one, it adds a really nice texture to it.
The skin is made from a well known brand 3M and is very precisely cut for every part needed, it comes with spare precut pieces for the camera and buttons. There's also two options for the screen which are, top and bottom or top, bottom and sides. I went with the full coverage.
Applying this skin was interesting because I am new to it. The screen was easy to do but doing the contoured back was interesting. It came with no instructions apart from going to their site and I, being the geek I am never read the instructions. So I go to stick the back on, line everything up perfectly but don't understand why it looks so bad.. After a hour or so, I give in and check the instructions. You must use a hair dryer for the corners of the back. After doing this, within seconds it was perfect.
This skin feels amazing in the hand, I use only it on my phone. Apart from the neglect to read instructions it was easy to install and is well worth trying if you don't like cases. It looks fantastic on the phone, it's like a whole new phone and you don't see them much.
