They are awesome! How accurate are any test kits really? Consider the margin of error when reading color charts. Tests are useful for detecting a change from a previous value. if your tank is happy and healthy, it doesn't really matter what your baseline is.
Having said that, they are very accurate.
I love the Hanna test kits.
