Hey Guys, I just received the premium leather back in Auburn from Valentine Goods. Slapped it on... and it's pretty nice. I got this as a hold-over until the SGP back protectors were released to the market. The adhesive is pretty strong so we'll see how well it stays on/in place with time as it goes in and out of my pocket. The Auburn color is a medium dark brown and is very nice. The only thing I wish Valentine Goods would do is round the edges so that they're not so "sharp". The only issue I can see is my fingers catching the edge as it goes into the pocket for the phone and peeling the backing. Anyway... I haven't decided if I'm going to keep it on there versus going with the clear back protector and a snap case yet... I'll give this leather back some time first. www.valentinegoods.com (I have no affiliation with them).
