Truth be told - I was cynical However, I'm pleasantly surprised. The strips work very well, and I can be 100% sure about this because I have my water softener connected to the hot water only. This is how I wanted it to be setup. I do not want my drinking water softened any more than it is, I actually have a separate filter for that anyway So, I did two tests, and as you can see from the photo. Green is the hot water tap result, and light brown is the cold water tap result. In a nutshell my hot water is soft, and my drinking water is mildly soft. Perfect! All-in-all a conclusive result and there are plenty of strips to last a very long time Would I recommend this product? 100% YES!

Very imprecise. Colors change and fade, and even if you manage to do it right, you end up with a wide scale between two colors and you have to estimate with a LOT of error margin. Buy an electronic tool instead, don’t waste your money on this.

was surprised by how simple these test strips are to use. The instructions are clear, and I got my results in about 30 seconds. The color chart is easy to read, making it simple to determine my water hardness level. The strips seem accurate and gave me confidence that I can properly monitor my home’s water quality. The package includes plenty of test strips, so it offers great value for the price. I would definitely recommend this product to anyone who wants a quick and reliable way to test water hardness.

Affidabile e si nota molto chiaramente la durezza del acqua

Simple to use and effective in my opinion. what else is there to say. It does the job I was wanting it for. Thank You.
