Love it
Color: Mattle Black
We'd been looking for a sponge holder we liked for a while andy wife came across this one. We were not disappointed. It's plenty big to hold a handful of sponges and scrubbers, plus our hand soap. I like the design that lets excess water drip back into the sink. Looks pretty low profile and sleek too

Keeps the water off your counter!
Color: Mattle Black, Color: Mattle Black
Works great! I’ve been looking for a solution to stop the sponge water from spilling onto the counter! Liked nice and neat. Great for keeping everything neat and organized. Size is perfect for sponges and nail brush and a small soap bottle.

I like the look of it, but the suction cups do not work well. Always falls off, into the sink.
