Good Compact Design
Color: Black
Attractive design and space to store the dish brush and or sponge. My only criticism is that the pump spout is quite narrow so the liquid soap skims over and not that much is released with each pump.

Bad product, cannot recommend
Color: Black
This product didn't work well at all. The material gets smudged and dirty extremely easily and it's impossible to get it clean. It's also very heavy, but not in a good way.
The pump shoots out dish soap very far and makes a mess on the counter. Even when I hold the sponge or brush right by the pump, the dish soap still went all over the place.
The pockets for brush and sponge did not work well either. Even the taller back pocket was way too short to hold a normal size dish brush.
I ended up throwing the item in the trash.

Went from five stars to three.
Color: White Marble Look, Color: White Marble Look
I was thrilled with this dispenser & sponge holder for the first month or two then soap started oozing out of the top. (See photo) I didn’t change types of soap but am trying different things now to see if it helps. It’s a great fit in my kitchen, holds the items I need, is sturdy, looks classy and clean but I’m not sure if I’ll get used to the blue ring of soap oozing out. I’ve been using this for 2.5 months at time of review.
