Mine also arrived damaged in one spot which fortunately isn't visible because I placed it high up. There is also a small scratch on the surface. Good otherwise.

The extra support bases are only included for larger sizes. The screws and the holder for the markers are hidden at the bottom of the box - I almost threw them away!

It is what I wanted but it arrived with two hits from the transportation, I want to believe, and the support bases were missing from the packaging

I got the size 60-90.
It is exactly what I was looking for. Essentially, it is a board with 4 holes, it does not include anything else in the package.
