The Case acts processed valent, is fortunately odorless and adapts to the body very well, there remain no disturbing gaps where dirt can collect! Overall a tacky feel, the instrument of course makes a few millimeters thicker and wider! All functional areas of the Nexus 4 (microphones, speakers, USB port, etc.) have a well-sized cutout get donated, so that everything remains accessible and usable. The only weak point is the button above the power button. Since it requires a little bit Nachruck to turn on the device, you "feel" no longer really the pressure point of the button. In the volume rocker on the other hand everything is fine.
Overall a good TPU case, it would recommend to anyone who wants to protect the noble and sensitive back of the Nexus 4 from scratches and other damage!
