In addition to the absolutely fast delivery, the quality in my opinion is super: The Bumper fits 1A. All buttons can be operated so as you're used to from the iPhone without Bumper - no restrictions with me, also the charging cable fits easily. In addition, from the black and white combination of the bumper looks far more interesting / more stylish than the pure black version. The actual purpose of the fulfilled Bumper then also: you can finally let the iphone store without too much caution on hard surfaces or even fall times and it is far more grip in the hand. Another advantage: the Bumper case for the iPhone 4 slightly thicker and fits finally without wobbling in my old iphone2G-holder in the car :) Conclusion: strong buy recommendation on my part (the price as opposed to Apple original Bumper is top, so does not need to be mentioned separately)
