Great kitchen organizer
I love this handy kitchen sink organizer! I like things to be neat and tidy. This little product does the trick! It holds my dish liquid, hand soap, brushes, disposal cover and my sponges. The size is perfect and it looks great next to my sink. The organizer is made of metal and is built very well. It even has a drip pan. No more stuff all around the sink. This keeps it all organized so well. Love it!

Just right for the necessities!
Very sturdy and made of quality material. Some people may prefer an even larger version if they use more products but thisone fits perfectly on the ledge behind my sink and is just big enough for the products I use daily when cleaning the kitchen. My only complaint is that the drip tray is about ¼ of an inch too short lengthwise so if all your products get a little water on them, you may get some drippage on the counter but I just slid it to the far left side where the sponges go because that's where it's needed most. I installed it backwards because I can't remove the tray from the front due to the sinks edge being raised too high. I also installed the rag holder in the opposite direction so that I can fit taller/more products in the back, I just think it works better that way imo. Overall, I'm highly satisfied with this product.

Noah's Ark
It's the largest caddy I could find that is great. Compared with other product reviews: no assembly required, sturdy, scratch protected feet, no rusting, etc. I bought clear and black spray, foam and capped bottles for it and just love having all my natural cleaning products out, handy, coordinating and looking good. Add a splash of color with some nice kitchen sheers or dish cloth. I like that it's not broken into a lot of compartments, but rather mostly platform to mix and match lots of bottles onto. I do have a long handled brush, and the basket holds it beautifully without tipping. I also found a silicone draining mat I like the look of, and it fits Perfectly under the caddy in place of the clear/white tray it comes with. https://www.amazon.com/dp/B0BHQ9MRZQ?psc=1&ref=ppx_yo2ov_dt_b_product_details Since I see this caddy set up every day, I'm happy to have a quality product on display.

Great product.
This stand works perfectly for me! Ive bought a lot and they either rust or the tray leaks water or you have to let the built in metal tray run directly in to the sink, which doesn't work if the sink is raised even a little bit.
This stand holds multiple cleaning tools, sponge brushes etc, the drain plugs and I can hang my cleaning cloth to dry. It is perfect. The tray catches all the water drips and cleans easily. It is compact and makes my kitchen counter look neat.
