In general, this shelf is good and capacious.  It is not difficult to assemble, but unfortunately, one bolt was not enough in my kit to fasten the door holder.  I took this detail from my old shelf.  Satisfied that this bolt fit the size and did not have to go somewhere to buy or contact the manufacturer.

Also, one shelf came broken.  It is a pity that it is from the front, but it is good that from below.  I decided not to change or return, because the shelf was almost folded when I saw it.
