Review on 200 Aquarium Test Strips Accuracy by Lexi Mastandrea

I think they are easy to use but it would be easier if they just worked. I dove in conditioned and unconditioned water several times and the results were the same, they didn't change much. The colorful squares disintegrate when placed in water, which is counterproductive and nothing seems to have changed. I don't trust them and frankly the information they give is so little. And as said, they disintegrate in the water and are therefore difficult to handle. Just buy the best test strips because they suck. 0/10 rating.
