First- I've really grown to like the bumper (had mixed feeling about it when I first started using it). I love the profile and simplicity. My problem is that it seems to continually lift the edges of my front and back skins. I'm running a wrapsol orig matte back-looks awesome - and the Zagg front cover- which I bought locally after having all sorts of problems with the wrapsol original front film- also looks very good now that it's been in place for a few days. Several times each day I find myself having to pull the bumper's rubber top/bottom back over top of the front and/or back skins. Just small sections here or there but noticeable. I would classify my use of the phone as pretty light so I don't think it's related to hard use. I am pretty anal about this stuff so I'm probably a bit more critical than others - but none the less it's annoying. I hope that over time the skin makers begin producing a larger version for the bumper. Possibly one that wraps around the sides a bit. These cuts would obviously look terrible without the bumper in place. One observation is that neither the Zagg or the wrapsol seem to be nearly as sticky of the BSE skins I've used in the past. Not sure if this has something to do with it or not.
