These are great! Im glad I ordered them.

I got exactly what I ordered}. The product description maches with what i received

If you use the API test kits then you may want to get these to go along with it. These are simply replacement tubes for the API kit so they are the exact same as what comes in the kit (clear tube with a 5 ml mark and a cap). And since they are somewhat fragile you will eventually need some replacements. Also helps out to have multiple test tubes if you are testing multiple tanks at once, in my case, 6. Its a lot easier filling a bunch of tubes at once for testing than using, rinsing and reusing the same few tubes over and over for one batch of tests.

These are a must when youre constantly testing aquarium water for different things daily. I dont like how fragile they are, so kits like this one are a must because the tubes easily break.

The glass is really clear (not cloudy like some other brands) and its great that the level line is marked off (makes measuring the amount for water tests super foolproof). I also bought some cheap plastic pipettes so that I disturb the tanks as little as possible, but more so because its really easy to fill up these tubes to the line with the precision of a pipette. The caps fit snugly and Im never worried about any leakage while shaking up the chemicals with the water during testing. To clean, I just run it through some warm water after Im finished with the testing and the tubes are as good as new again. Great product and I love testing my aquariums water quality with this more precise method.

Two original tubes were broken during the tests. I hope these last much longer. Good price.

after breaking most of the test tubes that came with my testing kit, I am so happy to find a perfect solution. Everything came and no tubes were damaged

Pretty good for the amount of test tubes you get for the value but some of them leak when you shake them

First, I hate that you have to buy a package this big. I wish they made smaller packages with maybe 4-5 tubes instead of 24. This was packaged very poorly. It was thrown into a huge box with some fish food I had purchased and had 1, I repeat ONE, air packet protecting the product. 3 out of 24 of the tubes were broken and there was glass all over the box. If I had received 20 or less I would have sent it back. Over all the test tubes are clean and the caps are very snug. I use these with my API master test kit. I suppose I will order again if I ever need to.
