I like the metal finish on this caddy. It looks very sharp on my countertop. It holds everything I need close at hand to the sink. The only thing I wish was different is where you can put brushes with handles. They fall through the metal piece at the bottom. I wish that part of the caddy had a solid bottom piece.
