This is a flashy little knob and we sell lots of them to furniture makers, BUT,as with many things in this world, beauty and utility are at odds. It is not this knobs fault. It might be considered cheap, but it is constructed as well as any knob in its usage class. It is just pretty and not sturdy. This knob is made for use on light weight drawers and doors in areas of moderate usage. This is not a knob that works in your kitchen with all those heavy silverware drawers and such. Give this knob light work and treat it nice and it will last a long time. But, there is no warranty or replacement on this knob. D. Lawless Hardware Listing and template services provided by inkFrog
