Functional neat and worth it!
Color: Navy Blue - 9.25″
This caddy has been even more useful than I expected. It instantly made my kitchen look cleaner and more organized compared to having wet sponges sitting on the sink. My counters look much tidier now, and the sponges dry out much better. It may seem like a small addition, but it really makes a big difference.

Makes the Sink Area All the More Organized
Color: Silver With Towel Rack - 9.25″, Color: Silver With Towel Rack - 9.25″
At first glance I'm sure most people might think this kitchen accessory is kind of silly; a caddy for your sponge and dish soap? But honestly, it makes the kitchen area look at the more organized and keeps things in place. I sprung for the model with the towel holder because I always feel weird about bacteria sitting in the wet microfiber cloth that I use for cleaning the kitchen countertop and my dining table. The little dowel allows it to dry very quickly.
The holder can be configured in a few different ways to accommodate your cleaning items. I like that it's wide enough to comfortably hold the large bottle of dishwashing soap I buy and it's the perfect width for Sponge Mommy/Daddy sponges.
I've had it less than a week and haven't had to wash it yet, but it seems like it will hold up well in the dishwasher and won't rust. Since I don't have any sponges on a handle, I may use the removable compartment for those (that you can see on the left in my photo) for other kitchen tools.

Un mess your kitchen sink mess
Color: Black - 9.25″
Just the exact right thing to gather all the sink doodads into one place. There is a little divider that is movable so you can adjust the sponge holder to your brand of sponge. AND it has a drain spout for the water run off. Very sturdy and handy sink catch all.

Great for organizing sink
Color: White - 9.25″
We had one of those suction cup sponge holders, but if you have tile that is not completely smooth, it falls down. This does not have that issue because it just sits on the counter or if you have a large sink lip, on there. You can move the inside pieces around which I was really surprised about because I thought it was all in one piece. Being able to move them around is great because then you can adjust it for your own soap dispensers, etc to fit your space. I like that it comes in a ton of colors. We got the white and it blends into our kitchen and looks really nice. This organizes our dish soap, sink drain cover, and sponges nicely and gives it all a space to go in. The tray on the bottom is silicon and removable which is great. I wish I had bought this thing years ago because it's great.

Great deal. Great product. Simple and efficient.
Color: Black - 9.25″
It is very simple to put together and it feels sturdy and I like how it looks. I know everyone's sink is different but it fits mine PERFECT. I'm really happy with this purchase. Good price good value. I don't see why you wouldn't buy it if this is the style you were looking for.
