I bought these to replace the knobs on my newly redesigned kitchen. I loved the style and they looked perfect with the new decor, however, after a couple of days of use they began to wiggle. It is not one solid piece, and it does have a small Allen Wrench fitting inside to tighten the wiggle, but who wants to remove the knobs and tighten the fitting every few days Needless to say I have ordered different knobs and these will go in my, someone may want them, pile.
