Just unpacked it and I'm writing on it with a special marker for these surfaces. I erase it with the special sponge I bought and besides the fact that the marker doesn't erase well and requires many repetitions to erase, in one spot the white glossy coating slightly came off. Attention, this happened only with the sponge trying to erase the marker.
Okay, I overlook the stains and the difficulty in erasing for a €10 product, but damage with a sponge during erasing is not forgivable, especially in the first 5 minutes of use.

I have been using this specific board for a month now (secondary board). I can say that I had several reservations with the negative reviews, but fortunately, I did not encounter any issues.

Positives
- It does not smudge the ink, even if it dries out, it does not leave any traces behind (cleaning with a sponge).
- It has a marker/sponge holder in the 1 horizontal position (but it cannot be placed on the opposite side or on the vertical ones).

Negatives
- The two hooks it has are not very stable, so many times the board moves left-right.

I can say that I recommend it as a board.
