Nice clutter catcher!
Color: Black, Size: Medium, Color: Black, Size: Medium
I've been using this for quite some time now since I purchased it I wanted to give it time to make sure that I actually used and experienced product before reviewing. I haven't really had any issues with it it holds everything it's been sturdy enough that when I'm doing dishes I can just push down on the pumps on it without any issues. The draining portion of it is a little Hit or Miss sometimes it drains properly other times it drains onto the side of it but I think that is just placement of the tray the one that I have it's not fully engulfing the whole bottom part so there is spots for water to leak through. The side rack is also convenient I use it to store my scrubbies and straw cleaners I did have to put something down to prevent water from getting behind my sink on that spot but other than that everything's been fine my sponges fit up underneath it fine. the only thing that would make it better is if it had a scrub Daddy or Mommy holder!

The Caddy fulfills it's duty
Color: Black, Size: Medium
This caddy turns out to be everything I hoped it would. So often I'll purchase an item and it turns out to be cheaply made or wonky. But this 2-Tier Kitchen Sink Caddy fulfilled it's mission and cleaned up my sink area. Everything is handily stored in it's compartments.
