Looks nice

It looks very nice. It has a streamlined design, not big and bulky. Quality is ok. I really like the look of it.

Compact
Color: Silver
Size fits well on back of sink. However, the bottom needs some kind of non slip traction as the unit slides a lot. Had to put something under it to keep from moving around.
