I have had 3 Sliders on 3 different iPhones. I have never had a Slider scratch the back of a phone. I have never had a Slider that did NOT scratch the chrome bezel. The roughest treatment my phones get is being carried in the front pocket of my jeans, with nothing else in the pocket. With the first case/phone, I didn't clean the case often. With the second, a little more often. With the third, every day. Didn't matter. Bezel got scratched, especially badly at the bottom, near the data connector. I've seen this theme in several different threads here, and many more people are in my camp than the fortunate souls who haven't experienced the scratches. Nevertheless, I obviously like the Slider, and would still be using one if the latest one didn't insist on bubbling my screen protectors. I use Power Support matte protectors, and can't make any of them work on this phone with this Slider. Anyway, good luck to you! Hope yours works better.
