WOW!!! The photo on line looks nice but when these arrived for real they were gorgeous. For the new kitchen I wanted glass knobs for all the cupboards with glass doors and these are stunning. Nice size and feel. Specs say these are made from K9 Crystal. I have no idea what that is but these are brilliant like real crystal. The chrome base co-ordinates perfectly with the other polished chrome pulls and knobs selected for the kitchen. I'd give these 10 stars if I could.

Pros: Terrific price. Rated for commercial use so I feel confident that these will stand up well. 
Cons: None.
