need a smooth sink surface for this to work
Color: Silver
Suction cups didn't stick to my sink and kept falling; to be fair, surface of my sink is textured.

Three months later, it's a keeper
Color: Silver
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.
