Works well.
Color: Black
As described, but I think I should have gone with the larger one. Works well and does the job. No runny soapy water on the kitchen counter.

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.

Pretty; sturdy; perfect size
Style: Contempo, Style: Contempo
Nice, sturdy little sponge and brush holder for the side of the sink. I was afraid my sink would me too small and spent lots of time trying to find a holder for the rim/countertop area. This one is not too big but fits my dobie and brillo perfectly. My sink is a little too short for a full fledged brush so when I tried to put in the brush I use sometimes it sticks up too much. That's really not the products fault so I won't subtract the score because of it. Also, I decided to put the holder flush against the side closest to me, instead of the side or the back of the sink. If I had chosen that location, the brush sticking out might not be an issue.

Yes the suction works on stainless steel!!
Style: Contempo
I've been through many rag holders before including a magnetic one, which broke. But the suction on this sucker (pun intended) is top notch! It doesn't slide around or come off or slide to the bottom of the sink. It just stays put which is so unique for anything with suction cups. The only reason i am giving it 4 stars instead of 5 is that it is quite small. I wish it were a few inches longer so i could easily fit two rags or sponges in the holder. But i have to jam them in and its not pretty. So for the price, i think it should have been bigger. Still a good product because of the functionality of the suction cups.
