Prakisch and safely

By folding technique down, you can open this cover with your thumb.
So very quickly and easily.
The device fits in like a glove.
The protection of the device is perfectly fine.
Of course, I do not throw the device against a wall or lay it down certain heights fall to the ground and then expect that it will not be damaged.
There was probably not well designed.
How long will it last, I do not know Nocht.
After about 6 weeks, no noticeable wear.
Storage or driving: inside pocket of the jacket or trouser pocket right.
