Unfortunately, the protective properties (falling, pressure) are not particularly, because the material is quite thin.
Against scratching, etc. It helps of course very good.
Fastening of Ausziehriemens on the inside (the front of the sleeve) is problematic when a screen protector is used.
It happened to me that the protective film of the iPod has replaced the insertion by the resistance of the belt below.
Very annoying, because the (good) screen protector was only marginally cheaper than the mumbi sleeve.
