The envelope is tightly all around, except for openings for camera / flash, microphone back, headphone jack and charger plug. The top and side buttons are below the sleeve, but is thinner at those points. So the pressure must cover a little tighter to run as before, but as you get used to it quickly. The shell is dark in my original. She has a deep dark blue and on the back of the HTC logo is difficult to detect even when exposed to light.
By far the best thing about this envelope for me, however, the knobs on the left and right almost everywhere along the narrow side. With which the HTC is comfortably in the hand and is very tacky feel, what with the true noble but very flutschigen - as a metallic - Original coat represents a significant improvement. So you can safely operate the HTC with a (women) hand.
All in all a very worthwhile purchase.
