Missing Dividers

Disappointed it was missing the adjustable dividers. Not great to hold dishwashing brushes. They slip right threw the side.

Sturdy. Built to last. It solves all the problems my old organizer had. Very satisfied.
Review for ARTLEO Kitchen Sink Caddy with Super Water Absorbent Diatomite Stone Sink Tray, Fast Drying Sink Organizer with High Dish Brush Holder Sponge Holder for Kitchen Sink, Stainless Steel This appears to be a sturdy organizer of stainless steel painted with a good amount of black protective paint. I ordered it to replace an inferior organizer of the same material (made by a different company altogether). This one solves the problems I had with my previous organizer which had begun to rust and break apart after six months of use. The narrow steel bars on the bottom shelf of this new organizer are supported by wider steel flats in the frame that will prevent them from breaking off the frame. (My old organizer bars broke because they were barely welded onto the frame and the repeated "pushing down" of my soap pump-bottle eventually broke them apart from the frame). The pads that prevent it from sliding across my counter in big waves (we live and travel on a boat) are secured around the steel legs as opposed to just being glued onto the bottom (like the pads of my previous organizer were, which fell off). There is no metal hanging over onto the sink edge to cause rust (like the metal that had caused rust with my old organizer.) The dish-brush holder can fit on the inside of the frame or it can hang on the outside of the organizer, which is nice because it makes more room if you have many tools that you like to use at the sink. And it can be compact if you don't. Be cautious not to remove the hanging part (dish-brush holder) too often because repeated wear can cause the paint to rub off and it could begin to rust. The "Water Absorbent Diatomite Stone" is new to me but it seems to be working just fine. I assume I will have to clean out the ridges of it as gunk forms there, but that would be the case with any sink organizer tray. I am very satisfied with this organizer, it is robust and it solves all the problems I had with my previous one. The price is on the higher side of similar organizers, currently priced at $23.99. All the best, Mrs. dr

Worth the purchase...
Color: Black
For the price, this cart is great. Easy to assemble. All tools required are included. It was also well packed by the manufacturer as my package was delivered on its side and I watched it on camera tip over onto the pavement. No damage to the mirrored shelves. Quite sturdy and it holds more weight than I expected without concern for breaking. Matte black metal finish disguises little scuff marks that may happen and extra parts were included. All holes and screws were properly aligned and manufactured so there were no issues. While it's all or nothing for the two bottle holders as they are a joined part, you can decide on one or two of the glasses holders. Took about 10 minutes to assemble (15 total if you count trying to get everything out of the boxes and accounted for).

Great Buy
Color: Black
I’m so impressed with the TUTOTAK Bar Cart! It’s stylish, sturdy, and incredibly functional. The 3-tier mirrored shelves add a touch of elegance while also making it easy to organize bottles, glasses, and bar tools. Assembly was quick and straightforward, and the cart feels very solid once put together.

Classy and easy to assemble!
Color: Gold, Color: Gold
I love this bar cart. It looks really nice and is the perfect size for my small space. I will say the gold color isn’t what I thought it’d be. The color looks a little cheap, I almost start to spray paint it the color I wanted so easy fix. It fits enough cups / glasses and bottles + decor. Assembly was easy and took about 30-40 minutes. I really like the wine rack feature!
