I've used this type of pH testing strip before and found it easy and accurate to use. No such problem with this product. The colour developed quickly and there was no doubt or uncertainty exactly what the pH reading was. Since I still have some of the testing sticks I was able to compare one against the strip. If you want to know your pH level accurately then this testing paper strip is the best by far!
