All-New 18 in1 Drinking Water Test Kit-125 Water Quality Test Strips | for Well Tap Test Kit Water Testing Strips for Home Drinking Water Testing,Hardness,Chlorine, Lead,Iron, Copper,Fluoride

Wasn't able to get the result I was hoping for in regards to testing the filter in the shower, but these seemed to work well and easy enough to use. Just take your sample with the included tube and add a strip. After a few seconds compare it to the chart and it'll tell you what's what. I was disappointed to see that the shower filter was basically the same reading as the sink water, but with a slightly better hardness reading. Kind of doubting the efficiency of the filter.

Very handy for RV when traveling, lots of different tests on one tab. It will also test the wholding tanks. Easy to read.

Exactly what I needed for my fresh water fish tank.

These testing strips work fantastic! They read accurately, they hold together well and read clear results.

Does absolutely nothing, tested it with tap water and multiple different brands of new just opened water filters, not only do you not see any change in the colors, the quality is terrible, you can see the colors bleeding off the strip as if they were just painted on, it's a terrible product.

Great job

I don't think its accurate

They work fine.

Gutes Tool zur Überprüfung der Wasserqualität. Wir haben es für unser Brunnenwasser gekauft und das war ist besser als gedacht.

始めて使ってみましたが解りやすかったです。 大型プールで使用してみました。

Excellent product. Worked well.

No issues with this product it was clear to understand the reading.

Buena calidad
