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!

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!

Perfect Product

Color: Black

What a great organizer. I used mine for a hand soap, dish detergent, sponge, scrub brush. All in an easy-to-use holder. It even has a pan under to stop drips and keep my counter dry!
