I have what appears to be the same case. I ordered mine off of Ebay only it came from China. It did take about 10 days to get here but it was also only $2.99 shipped.
TPU Gel Case Cover Skin Stand /Screen Protector For Samsung Galaxy S3 III i9300 | eBay
I like it, a lot! It fits very well, holes all line up, buttons work pretty well. It's very comfortable in the hand and doesn't add too much to the bulk of the case. While I've only used the kickstand a couple of times it can come in handy from time to time. And while it does stick out a little from the back of the case it doesn't bother me at all. About the only complaints I would have is that depending on which micro USB charger I'm using, it can be a little difficult to plug into the USB port. I use 3 different chargers depending on where I am and one doesn't fit easily while the others do. Also, because the area along the edges are textured it's a little difficult to feel where the power button is. It sort of blends in with the surface around it even though it is clearly set apart from the surrounding area. It's not so bad that I can't deal with it but there have been a few times when I went to turn it on or off and sort of missed the button. That will likely change as I get more used to the case. Seeing as I have about half a dozen cases to choose from it's going to take a while to get used to this one. But so far I've used this one more than any of the others.
