Buying these is like playing Russian roulette. If you get a good one, like a friend of mine's, they are well worth the price. But the one I received had parts that did not lock together and the rotor wobbled. I returned it.

Ex Output:
negative


Ex Input:
Read all the great reviews, so bought this item. Instructions are extremely inadequate; could not figure out how to put together. Returned immediately.

Ex Output:
negative


Ex Input:
Got this case a couple days after the sale processed. Got a lot of cleaning supplies with the protector which was nice, and the packaging the hold the screen protector was very sturdy and secure. The ease of installing was very simple. Steps are clearly labeled and easy to follow. Screen fit perfectly around the home button and corners. No excess so didn't have an issue with the screen peeling up when pulling it in and out of my bag. Screen sensitivity doesn't get affected at all, it actually requires less pressure now than without it. I will suggest this to any one who is in need of a great screen protector.

Ex Output:

positive
