Great design for a kitchen sink organizer -- will not tip or accumulate water
We've had an Oxo kitchen sink organizer for years, and it's been fine, except 1) tall brushes (for example, Oxo brushes) make it tippy, stray elbows or imperfect placement of the brush would knock it into the sink and 2) it built up a soapy sludge in the bottom that that had to be drained and wiped down constantly. This item solves both issues perfectly.
Likes:
Size - I think it's about 5 inches deep, which is just right to fit the strip of countertop that runs behind the sink, up against the backsplash
Weight - The drying stone in the bottom gives the baskets some real heft, so there is no tipping it over by bumping a brush handle -- it really stays put
Drying stone -- The diatomaceous drying stone that slides into the bottom of the main basket is a great idea. These are porous stones that will absorb water and then allow it to evaporate fairly quickly. So far, it seems to be doing its job well. I'm sure the stone will need a wipe down now and then to stay clean, but no puddles of sludgy soapy water in the bottom is a big plus
Overall Design/Build quality -- The unit seems solid. It's a simple design, but there are no sharp edges or unfinished bits. Once in place it doesn't wobble a bit. I wasn't sure about the black powder-coated finish, but installed it looks clean and it's unobtrusive. I appreciate that the smaller basket for tall brushes sits on hooks and can be hung inside or outside the main basket. Ours sits inside, but there's plenty of room left over for sponges . And there's still room to stand up a bottle of liquid detergent or counter-top spray.
NOT SO LIKES
Nothing so far. I notice a lot of this style of sink organizer on Amazon, so presumably they're selling well. It's a great improvement over the older kinds.
Five big, clean, well-organized stars. Highly recommended.
