Good Quality but Limited Space for Multiple Bottles
Color: Black
This organizer is decent quality, but it ended up being smaller than I expected. For reference, I usually keep the following items at my sink: • Dawn squeeze dish soap • Mrs. Meyers hand soap • Dr. Brown’s bottle soap • A sponge • A bottle brush All of these items fit comfortably in my previous sink caddy that I bought on Amazon. Unfortunately that one eventually started peeling and rusting, which is why I replaced it. With this one, the narrow section on the left side limits how much you can actually store. It works well for the brush, but it reduces the usable space for bottles. Because of that, fitting multiple soap bottles plus a sponge is a little tight. I also think my previous organizer was slightly wider, which made a bigger difference than I realized. One feature I do like is the removable plastic tray on the bottom. It catches water well and keeps the counter from getting messy, which is a nice touch. Overall, it’s usable and I will keep it, but if you normally keep several bottles and tools at your sink like I do, I would recommend paying close attention to the measurements before ordering.

Fits well in any space
Color: Black
This is a great little caddy. It sits nicely in the small area I have and keeps all my stuff organized. The tray comes out to clean it.

Wonderful size and holds the essentials.
Color: A-silver
I have no room for something bigger because I have a drop in sink. This is working wonderful. There is room for a scrubby, sponge my stove top cleaner and scrapper for stove. The tray below to catch any water is great and very easy to remove and drain. It takes a second to do. Great size as it is not huge but holds what I need.

Good caddy, not a fan of the clear water holder. Should be black like the caddy. And maybe another taller area for the sponge
