Here is my review for it. I posted this on the SGP website and has been queued for moderation.
"I've had the Leather skin guard for a week now and I'm not too happy with it at all.
The application is simple enough. With its' sticky surface, the edges are sticky as well and it will end up collecting dust and fabrics.
The size is the most disappointing factor. It is not flushed with the back edge of the phone, but about 2mm smaller on all sides leaving it exposed.
It's a very thin piece of material which is neither good or bad. However, in my opinion, it should've been a tad thicker to emulate a softer leather feel.
Overall, skin looks like leather, feels like leather. But doesn't provide the right measurements to protect the total back of the phone. The adhesive is a bit sticky and can cling onto fabric threads. I wouldn't recommend it until they resize the skin guard to the appropriate size."
I just ordered a ZAGG leatherskin. Hopefully it comes in about a week or 2. I can tell you how it works with a bumper =)
