The tablet shuts down so it "sticks". I don't think we need to say anything else. (It's not about on/off, etc. it just shuts down).
Don't buy it.

The reason for the 3 stars is the keyboard. I would give it 2 stars, but I gave it 3 because the case is relatively good and it has a case for the S-Pen as well. However, the keyboard is terrible. The keys require a huge amount of force to be pressed, and if you are a fast typist, it misses half of the letters. Also, you need to press exactly in the center of the keys.
