The only reason the Slider did not last on my iPhone was because I am using a screen protector, thus the edges of the Slider pumps the screen protector upwards trapping air bubbles underneath it. I tried repositioning the screen protector but no go and my friends faced the same issue as well with this case.
I have both the Rebel and the InCase Slider. The Rebel will help protect it if you drop it (which I did ) As far as the Slider, I'm using it right now and I've had no issues with it "lifting" the screen protector. The Griffin Wave Case is a good choice as well.
I love my Case-mate touch-through case and the full protection it assures (including the screen). Moreover, I have been very much impressed by their customer service.
