The cover is not too bad, but very low quality. The screen protector is the worst I have ever seen, so bad I have just ordered a different one. Not only it leaves bubbles, but it makes the sliding motion on the screen very difficult. Don't waste your money.
Bought this case for my GS3 and I like it. It replaces the back cover with a better thicker back cover and also has a screen protector which is connected to the case. You can also continue talking on the phone while the flip cover is attached to the screen because it has a speaker grill hole.
Keeps the phone slim too, perfect for me.
