Really good folding, I would buy immediately! I was sick of it, that the 4-folding boxes to break already start from the grocery store after a few weeks. This one is very nice stable, you need have no concern, even if you even want to carry drinks or other heavy objects. The long sides however dents from noticeable when they are under pressure. This is ugly, but at least in the medium term no stability problem .... I also have, on several occasions handles centrally missed the long sides in the three weeks that I have the box. These two points move me to deduct a star - even if I would not buy the box at any time immediately again!
