I bought this kit after constantly hearing the news about drinking water pollution in my area and I am very happy with it! And so I found that my Britta filter is useless as the total amount of dissolved solids is almost the same as before the filtration. The pH meter comes with 3 calibration bags. I've compared the readings to professional TDS and pH meters and they're pretty close. So overall this is a great home water test kit for the price!
