That the design to 350kg can be loaded, might be true, but if the dowels (not supplied) hold in the concrete wall of my bedroom in the long run and not yet Mr. erupt someday, I do not know.
My walls are somehow very "soft". To me it has already happened that a wall unit is thundered men's because the anchors are broken out of the geborten holes.
All in all, the product is absolutely worth the money.
