Fits my needs
Color: Light blue, Color: Light blue
I purchased this specifically for the garbage disposal side of my kitchen sink. I only needed it to hold my sink stopper. I haven't used th basket yet, but will probably use it for a steel scrubber. It's a little on the small side, but it works great for me.

Perfect size
Color: Black
Fits the little spot we have in our kitchen very well. I tend to not measure and just hope for the best. Easy to clean and hasn't rusted yet. Does a good job of draining and letting things flow down

Great product at a good price
Color: Black, Size: Medium
This sink caddy is made of sturdy material and helpful for holding the stuff on the edge of my sink. It's nice to be able to move the little drain spout to accommodate where I set it. It also allows me to move the divider to accommodate the size of what I put in there, so that's nice. It has an overall nice look. removing the tray to wash it out is very helpful. The only thing I don't care for is that sometimes when I grab the dish cloth, the little rod pops out. However, this is a minor inconvenience, and only when I'm in a hurry to grab the cloth. The price is very reasonable for the sturdy material.

Keeps my sink area neat and organized
Color: Black, Size: Medium
Really happy with this sink caddy! The 304 stainless steel feels sturdy and looks nice, and the auto drain spout keeps water from pooling on the counter. The divided sections easily hold my sponge, brush, and soap bottle without taking up much space.
I also like the removable towel bar and that there was no installation needed. Redy to use right out of the box. Simple, practical, and very useful for keeping the sink area tidy.
