For my taste is really annoying that the hardware buttons (volume, power) of the sleeve intended to be included (presumably to protect and prevent them from being pressed accidentally). That means that every time a comparatively much too great amount of force is needed to actuate the keys. That goes especially for the power button at all, since this is required every time when you want to terminate your cell phone (ent), which quite often is usually the case.
This problem can be but 5 minutes and a utility knife easily fix yourself.
