Very pretty
Color: Black, Color: Black
This sink caddy is very pretty. It is easy to use. It has slots for brushes and whatnot. Keep in mind that not all soap bottles will fit in it though. I had to adjust my soap bottle to fit, so it kind of took up space where I could have put a little more things that same space. If you have round sponges like the ones I have, they can fit where you put the soap dispenser. It just all depends on what size soap dispenser you have in there. The quality has been good so far. It's easy to clean the bottom of the tray. It simply just slides in and out. Very easy. I recommend this.

Great for those who have little to practically no counter space
Color: Black
For such a small item, it holds a lot. It holds my regular scrub brush, my cast iron scrub brush, my green scour pad...two of them, my dish cloth any my nylon scrubber. It takes up little room, but keeps the sink area from looking so cluttered Update. While the body of this unit is still in great shape, the bottom has rusted so bad it broke. I will be buying a different caddy.

Beautiful, but not as durable as expected
Color: Black
We’ve been using this soap holder for about a year and while it is functional and fits our space nicely, it’s starting to rust. I’m a little disappointed that a product designed to hold wet sponges and soap doesn’t have proper coating to prevent rusting. Other than that, I love it. The tray catches runoff and easily rinses off. It home all my bottle brushes, two glass soap jars and my sponge. The design is pretty and matches my other kitchen products.
