yea, the only 2 things i dont like about tipbs bumpers are the hard to press sleep button and the clearish color to it. if it was a solid color it would be alot harder to stick with the apple bumper. my apple bumper doesnt slide around that much though, guess i got lucky lol..only problem i have with the apple bumper is i cant use my iphone 4 dock i bought like 2wks before they offered the free bumpers. wasnt gonna spend $29 on apples bumper...im satisfied with apples bumper and i still dont think i would pay $29 for one...although maybe if they made a yellow one lol. honestly i dont even like cases i only have the bumper on because it was free and it stops the glass on the back of the ip4 from touching the surface. the little noises the dust and dirt inbetween the glass and surface scares me lol
