> 3 dayThe 6 replacement API test tubes were just as I expected. They all arrived intact and I have been using them for their intended purpose (testing the water chemistry of my fish aquarium). I would purchase them again if needed.

> 3 dayExactly what I was looking for. I guess I’m clumsy cause I broke 3 out of the 4 from the kit in less a week. Wish they were plastic.

Greater than one weekThese did not come in a box. They arrived in bubble wrap with one broken into a bunch of tiny pieces. The glass is very thin similar to the ones in the testing kits. They break VERY easily. Would not buy again.

> 3 dayClearly marked for accurate measuring. However, the tubes are a bit small for the conventional test tube rack and fall to the bottom. They should indicate the dimensions on the box so an appropriately sized rack could be used. Otherwise indispensable.

> 3 dayThese replacement tubes are identical to the ones that come in the API master test kits. In my photo is one that came with the master test kit and one of the replacements from Amazon set side by side. Honestly, by the time I had taken the picture I forgot which was which. If youre prone to clumsiness like me or just want more tubes these are a great purchase. They arrived packaged extremely well for transport and none of them had any flaws.
