It is almost great.
Color: Black, Size: Medium
It is a nice sponge holder but the tray is not wide enough and it falls. Because it was the only one I found with a spout, I am keeping it, and figured a way to stick it so the tray doesn't fall. The other thing is that the tray is not sunken enough in the middle for all the water to be routed there, and the spout doesn't always get rid of all the water inside, so once in a few days, I have to manually press it down and more water comes out. The dishcloth rack is not great for cloths, they get wet. Other than that, it looks very nice, it is aesthetic, big enough for all my kitchen stuff, and makes my kitchen neater, so I like it.

Love this product very convenient
Color: Silver, Size: Medium
This was great to keep all my brushes, cloth, detergent and scrubby together and neat. I love the drainage and it looks clean. The only thing I don't care for is the bar that holds the cloth comes off all the time. Other than that it is great.

Beware of a sticky detail
I was looking for a way to organize my kitchen soap, sponges, and bottle brushes. This soap dispenser checked off all of my boxes with a nice stainless steel design making it a great addition to my kitchen counter. Question: after all of these positive aspects why only two stars? Answer: there is a sticker placed onto the dispenser that is so sticky that it is a formidable foe to remove (please review the attached photo). I liked this soap dispenser but the semi permanent sticker is the deal breaker to an otherwise nice product.
