The case is very good. The problem with the screen closure mentioned by others is fixed in the tablet settings, where you disable the smart cover function!

After purchasing the case, I noticed the issue with the screen closing when I place the back cover. It's a bit annoying but it's very good for its price because there aren't many cases available for this specific tablet.

The case does not fit perfectly on the device, it goes in with relative difficulty but remains in place. The issue with the screen closure that other users mention is real, I am attaching a relevant video. It is a cheap case but it might annoy you. I did not return it solely because I threw away the packaging.

The magnet of the case is great... a pretty stable base. Comparable to other more expensive Samsung ones that I have used on previous devices. Now, some other reviews I saw about the magnet, my friend, in order for the magnet to work, you have to put the tablet inside... the base magnetizes to the back of the tablet, not on the case itself... and the screen unlocks just like in all the corresponding cases when you open the lid and locks when you close it... a worthy choice for its price.
