I can only agree with some people before. We now had a direct comparison. The existing heavy duty shelves are something solid, not so sharp and especially not as "flexible and wobbly". We have to keep it now because we urgently needed as a shelf. But unfortunately, the note is if at all only "satisfactory" rather SUFFICIENT. We can not recommend for somebodies wants it actually as Schwerlastregal use this shelf. For light stuff and then stow suitable.
