I don’t know what happened with my first two reviews but my opinion is still the same. 
I love these knobs. Unlike other clear knobs I’ve tried these have a “metal” base which I’m hoping with help last longer plus it really gives them a more sophisticated look. 
I’ll need to get some shorter screw for the two (2) doors on the upper unit but I’ve found a temporary fix until I get to  the store. 
I only needed four (4) for my bathroom but this set comes in a group of ten (10). 
Win Win… replacements if I need them or extra for other projects.
