Good
Works great, but bought by mistake. I searched Amazon for Hanna Nitrate checker and this came up as the only one. I did not notice this was a Nitrite checker until I opened it. I will keep it, but dont need it. Getting old is not fun.

Hanna is the way to go for accurate tests
Hanna testers are the most accurate consumer grade (affordable) testers. Price-wise, they are exactly the same every place I’ve seen them. Hanna has set the minimum advertised price at $67.99 so that’s what they are whether you buy them at your local fish store or on Amazon.

Check test kit for it being previously opened or used.
The test works but the text kit was already opened. The battery was already installed, the dropper is missing, and there are only 4 test packets. I ordered a replacement and will send back this test unit. Itâs expensive and I want to make sure I get my moneys worth.
