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.

Aesthetically pleasing
Color: Black
Very aesthetically pleasing, easy to clean, will last a lifetime because of the material quality and it feels like stone more than plastic.

Attractive and works great. Be sure to clean the suction cups and sink before using!
Style: Scroll
I have wanted a sponge holder to put inside my sink for a while now. I wanted something attactive and I wanted it to work as it should. Seemed reasonable until I started looking and reading reviews. The biggest complaint appeared to be that these sponge holders do not stay attached to the sink. The reviews for this particular holder were great. Customers stressed cleaning the suction cups and sink before using. I am really glad they did because holder arrived in the packaging with zero instructions. Because I read the reviews I knew what to do and it worked! I am very pleased with this sponge holder. It is attractive, it feels really sturdy and it stays on the side of stainless steel sink just fine.
