Product Testimonials

Thank you to our recent customers!


Bought 3 test kit caddies for ALK, PO4 and NO3. They are all designed to tight tolerances so that there is no play in the components they’d housed. Plus they are precisely color coordinated too. Impeccable quality to say the least!

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.

Works great, easy to clean, very functional. Nice how the vials air dry, super convenient. Great product overall!



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.
