Wonderful, roomy caddy
Color: Black
I don't usually write reviews, but this is a great product to share. This sink caddy is everything they say it is. The bottom drying stone protects the counter surface from getting wet and sponges, etc. dry in a reasonable amt. of time. I love the basket for tall items like brushes- enough room for two- and the removable partition to use however one wants. I debated getting this longer one, but I am glad I did because it fits quite a bit. I even use the one side with the partition for a spray bottle. It also looks very nice and feels like a quality product. I wasn't sure if the black metal would go well with my beige countertop, but it looks great. I highly recommend it.

This organizer is awesome!
Color: Black
This sink organizer works great! It fits everything I need to fit and works well on my countertop. The diatomaceous earth stone underneath collects all of the water and there is no puddling underneath. I love the divider because I can keep my sponge separate from my bottle of dish soap and brushes… 10 out of 10 would definitely recommend this item!

Go big
Color: Black
I had a very small holder that barely held anything, the I stumbled on this in the small size, which I almost bought because it was a little bigger than what I had. Then I saw this one and I'm glad I bought the larger one because it holds everything! I even bought a glass container for the dish soap. Fits perfectly in the space. I also like the idea of the stone to absorb water instead of it dripping in a tray that runs through a spout into the sink.
