fair
Color: Black-l
Good caddy, not a fan of the clear water holder. Should be black like the caddy. And maybe another taller area for the sponge

Recommend this it’s awesome !!!
It’s awesome and it works great. The old one I had from Walmart kept getting clogged. It wouldn’t work right this one has yet to get clogged. It holds two of my sponges that I was hoping it would hold a lot easier to maintain and clean, and the pocket was able to hold both of my scrub daddies.

Just what I was looking for
I’ve been using this for a while now and I’m glad I chose this one. The pump action is great to keep filled for easy use. I have 2 sponges on it and on the right side I keep a bottle brush as well as a squeeze bottle of dawn. It is a really good size! Good value and very functional for my needs.

Good enough
This item does the job but if you place wet items into the pocket, it will leak that water out the bottom, leaving your counter top wet. Otherwise, it works fine.
