Nice product with least price!

They are helpful.

Excelente para medir el ph de mis productos de cosmética natural y también puedo medir el ph del sustrato de mis plantas.

They work

I bought these to test my alkaline water system to make sure of when I need to change the filters. I also tested our alkaline system that my boss (a doctor) installed in our office. Both systems test to be at least 8 on the pH scale. These come in very handy because it’s important to know if the systems are functioning properly.

I used only three of the small strips with regular tap water. No color change, except for the last of the three tested. On the third after completely drying out, I saw three small colored dots. I have used another brand a thought I'd try these since the price was sooo much less than my usual brand. I got what I paid for, money and time wasted.

I have tested several different waters including our tap water and everything gets the same rating????not sure how this could be right!

This product is easy to use, covers a very wide range of pH, and seems quite economical. So far, so good. It remains to be seen if the shelf life is limited. Pleased this far.
