Good product
Color: Black, Size: Medium
It is as described, looks neat and tidy on the sink. Just big enough to do what I need it to do. My sink stays dry because the wate goes back int the sink.

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.
