Holds a lot, doesn't soak my countertop
Color: Grey, Color: Grey
Where has this wonderful organizer been all my life? I've always struggled with keeping those little suction-cup organizers reliably attached to the walls of stainless steel sinks -- after a while the cups always fail. But this organizer is just large enough and has room for every scrubbing item I want to grab in a hurry. And there's never water pooling under the organizer and soaking the granite countertop because there are little foam feet on the underside. It even looks classy. I just love it! Only time will tell if this organizer is durable. So far I haven't had to clean it.

Almost perfect sink caddy
Color: Black, Color: Black
My old reliable sink caddy had rusted through and I ordered 3 different replacements that I ended up returning. You would think a sink caddy would be very straightforward and simple - however I had certain things I needed out of it. What I like- -the large size. I don’t love having a million soaps but my husband recently got diagnosed with psoriasis on his hands. We tried Castile soap and water in a pump, and several free and clear types. He’s always working in the yard or cooking and we need them ALL out and accessible. Plus needed room for our actual dish washing soaps and brushes. Even if you have a normal amount of soaps - you could easily display a spray or other cleaner to fill this caddy up. -the tray. This one was important. I returned several others bc their plastic tray or absorbing stone bottoms were too small. The caddy would overhang and your soaps would trip out over past them. This stone tray has a little lip that goes all the way around like a border for your caddy. Most of the drips of water stay confined to the tray. (Unless you have splashy kids washing hands & dripping everywhere). But it’s mostly contained. -absorbing tray. This tray does not require you to empty the water out each day so it doesn’t over fill. It absorbs the water. I don’t know how. Maybe magic. But it doesn’t over fill and it doesn’t leak on the counter. If you have dirty splashes or a dirty scrub brush dripping down - it can leave some brownish marks. I take my soap out once a week and wash the caddy down and scrub the tray and it’s good as new. They included a small sand paper to use if the tray ever loses its absorbing power- you can lightly sand the stone and it’s supposed to open up the pores and be more absorbent again. I’ve only had mine a month and it’s not been an issue yet. The tall, removable brush caddy - while I do wish it was a teensy bit taller - it’s still taller than any others I tried. Your brush will have to lean a bit unless you have multiple brushes helping to hold it up. We basically use one brush and a straw cleaner and I have doubles of each. I keep 1 set out and 1 set in my dishwasher and I switch them every day. But there is room so if you need bottle brushes or scrubbers you could fill it up. You can also remove that little basket entirely if you want. And it has a hook on the back of it so if you prefer - you can hang it off the front of the caddy instead and have it overhanging over your sink instead. My sink is very rounded and it’s tough to display a caddy so that the soap is all accessible but it’s also not overhanging too much. The weight of the under stone tray doesn’t allow it to tip over into the sink or move. They also included sticky protective pads for the bottom of your stone which protects your counter tops and also makes it non slip. Over all I love and am very happy. I hope it doesn’t rust over time. But I would purchase it again. And if they made attachments for it or taller brush basket add ons I would purchase those too. Thanks for reading my ridiculously long review for a simple sink caddy. But if you’re very particular about things like me, I hope it helps!

Works well.
Color: Black
As described, but I think I should have gone with the larger one. Works well and does the job. No runny soapy water on the kitchen counter.
