I purchased the GH, KH, NO3 and PO4 test kits. I've always trusted Salifert when I had saltwater and wanted to try the freshwater line.
While the tests are easy to perform and read, in my experience, they need to improve on their quality control. My KH test kit came with a bottle without the drop top so I couldn't "count 4 drops" for the test. My NO3 test kit came without a measuring spoon so I couldn't add "a level spoonful".
Other than that, I think they are quality kits that are easy to use.
