Varify 150 Strips Water Hardness Test Kit - Water Testing Kit for Home, Drinking, Well, Spa, Swimming Pool, Softener, Dishwasher - Hard Water Test Strips for Calcium, Magnesium (0-425 pmm, 150 Strips)

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!

Great value.

Highly inaccurate - it rated 350+ ppm hardness water from the tap (per local area water reports) the same as soft bottled water. Not fit for purpose - spend your money elsewhere, I'll certainly have to.

Very hard to distinguish the colours. It also comes up with a different (about 50 lower) hardness than a liquid test kit. (OK, the liquid might be wrong but it is the one supplied by the softener manufacturer, so I'm inclined to believe that. I guess I'll have to get another tester to try and get a 2 out of 3 result.)

These are perfect especially for me as had an issue with our watersoftner, purchased these at a ridiculous price we'll worth the money.

I've been waiting for something as simple and easy as this ever since I've had a water softener, so 15+ years. It's really easy to use, doesn't need batteries and this batch will likely last longer than I will. Great value too.

Does what it says on the tin. No.issues and easy to use to yest hard and soft water

It is VERY hard to use unless you have perfect colour vision There are minute differences between the colours the tested strip turns, and the colours printed on the chart are far more saturated than the strip colours; this makes comparison even more difficult. Save yourself the money and go to your local water company's website; there you will find an extremely accurate value! In the internet age, his product is as pointless as horse whips became a century ago.

Easy to use and accurate. Results were quick and easy to read. Great value!

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.

Affidabile e si nota molto chiaramente la durezza del acqua

These water hardness test strips are quick, accurate, and very easy to use. The color chart is clear, and I got results in about 30 seconds. They work great for checking tap water, filtered water, and my water softener. With 150 strips included, it's an excellent value for the price. I highly recommend them for anyone who wants to monitor water hardness at home.

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.
