Good workmanship, but ...

The leather bag itself is very well made. The mechanism also works with the tab.
The problem is, unfortunately, that the bag is a little too small, so that the phone's side keys push are pressed, what ever may cause the phone restarts unintentionally (Increment by prolonged simultaneously pressing the power button and volume button).

UPDATE: Shortly after creating the review, I received an email from the seller and was delivered a spare bag for free and uncomplicated. Thanks for this simple service.
It's a little better, now it happens only sometimes, that when listening to music the volume is changed by the bag.
For people who need the bag only to protect, it is optimal.
