These test strips work perfectly and give quick, clear results. I used them to check the hardness of my tap water and my softener system — both readings were accurate and easy to interpret thanks to the color chart. The included eBook is a nice touch, explaining water hardness and maintenance tips in simple terms. With 150 strips, it’s an excellent value for ongoing testing.
