Fragile Product...Sub-par Packaging
By Steve on Jun 9, 2021
The extra supply of test tubes is much appreciated. However, the box the tubes were in had no cushioning whatsoever, nor did the shipping box. The tube box had opened and the tubes were scattered in the shipping box. Surprisingly only one tube was broken. The shipping box also contained an LED clip on aquarium light. I still recommend the products, but was disappointed in the lack of cushioning, both from API and Chewy. I still would order again, though. Just hope for better packing.

Great service
By Stacy on Sep 30, 2020
I trust Chewys for all my pet needs. It only takes a day or 2 for my orders to ship. I don't get charged till the items are on the way. I like that I can order prescriptions, and I love the way they keep me informed about the products and services. Buying at their phone app is so easy to navigate thru.

When you have cats...
By Delilah on Oct 14, 2018
Replacements are necessary. My furry little friends love to knock over my test tubes...I now have a test tube rack because I was afraid they’d go to jump off the counter and come in contact with the broken glass! These are literally the same test tubes you get in the API test kits so I’m very happy to have them.

Nice to be able to replace broken tubes
By BassetMom on Jul 13, 2018 top250Contributor
The second time I used my API kit I broke a tube. I got these and it has helped to have extra tubes on hand. I can also test all my tanks and then clean all the tubes instead of between each tank. It would just be nice if it wasn't so easy to break the tubes.

Great Replacements
By Halfpint63 on Jun 4, 2018 top500Contributor
Accidents happen and it's always great to have these extra testing tubes on hand. Besides using them for Test Kits, I use them to store my Frozen Foods for the Marine Tanks and Freshwater Tanks, makes using the pipettes so much easier for proper doses.

By CarpeDiem on Sep 22, 2017 top100Contributor
So glad I did not have to buy new test kits just to replace old tubes! This is a winner!
