These are beautiful. However, they are not made very well. I only used these 1 time, to discover these screw was coming out where you expand the tray. I tried to tighten they screw, to discover it was stripped. I looked at the other trays, and 3 out of the 4 were stripped out in the very same location. There is no reinforcement for the screw, for the amount of pressure that is placed in the particular area. 

Pros: Beautiful in appearance 
Cons: Not made sturdy enough for actual usage
