The product is well made and stable. Unfortunately, the design drawing stored here in the Internet shop regarding the holes for the mounting screws proved to be defective: The nominal diameter of the hole is not as specified 5.2 mm, but only just under 4.5 mm.
I used it to build a mini foldable table and they just bended when screwed into the wood table surface. Not sure that it is stainless steel since bends really quick.
