Just like the awesome Phosphate Test Kit Caddy, this one helps me keep my counter space clean and follow the test kit instructions without clutter AND stores everything neatly/visibly. Awesome Caddy and excellent customer service!

These caddies have a purpose built design and are superior to the other caddies available on the market. It is clear that these caddies were produced not only by a person in possession of a rapid prototype machine, but also a keen sense of design and engineering. Color me impressed.

Bought 2 of these and love them. Well built, nicely designed and easy to use. Made testing easier, by eliminating one more friction of unpacking and packing the tests. I like them so much that when Dmitry followed to see whether I was happy with the caddies (nice touch) I asked him whether it’d be possible to do ones for API test kits. Included in the package was also a cute thank you card which my daughter loved. Overall a nice product from a nice person.
