Tested our tap water before installing a new espresso machine, and the results were clear and easy to read within minutes. The included hardness chart made it simple to understand exactly what filter we'd need.

Finally know exactly what I'm dealing with for my coffee machine setup—the test strips made it super easy to read the total hardness level in under a minute. No more guessing about water quality.
