I got this because I wanna test the water regularly to keep track on how it is going. It is very easy to use and I still remembered using them from the chemistry classes.

Only need to soak a test strip for a few seconds and then the colours will change. The pack bring a colour chart, so you only need to compare the colours you got with the chart to find the result. It is very easy to use and I find the results fairly accurate. Therefore I recommend this pack of pH test strips!
