I hate it when reviews are left one day after the product arrives. At that point, there's no way of knowing if the item is going to last. When my last sink caddy went bad (the suction cups rotted out and the wires had started to rust), I ordered this as a replacement. Inexpensive, functional, worth a try. There were two things that impressed me when this arrived. The suction cups weren't permanently mounted, so if they fell apart, the caddy was still worthwhile. Secondly, the company offered free replacement suction cups if the time came I needed them. That struck me as above-and-beyond; I had no idea this was part of the package. I'm happy with this. It looks good, I detach the sink caddy regularly when I want to move it out of the way, and it pops right back into place. For the money, I don't think you can beat it.

Great caddy. Well built.

Color: Black, Color: Black

This is a great caddy for my sink items. Holds the dishwashing liquid, hand soap, sponge, brush and still has room for more. The only suggestion is to allow the brush cage to also be above the drip pan so you have more space. I know I can add the brush cage into the main compartment to drain it but I prefer the extra space. This is very sturdy and is the perfect width and height for many sinks.

Well made, well thought out!

Color: Black

I like that the caddy has a bottom and that the drain is movable. The adjustable separator is also a plus and I can move the tall attachment inside so that I can keep my wet brush there and it will drain into the sink.

Good organizer!

Color: Black, Color: Black

This is perfect for keeping all my sponges and brushes all in one place! I love when things feel more organized. I also really like how the excess water drains out of the bottom back into the sink!
