Bumper fits very well to the iPhone 4, is tight and can be easily removed anyway. But would not buy it again because it was eingilbt yellow after some time and also from the outset not as clear and transparent as in the photo. In addition, collects, as with most silicone cases, sand and small grains under the bumper, which make slowly but surely scratch the metal. Protectors can, depending on how they are glued, are slightly lifted.
