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.

Produkte wie beschrieben. Funktioniert einwandfrei. Nicht zu beanstanden.

Fast Delivery/Affordable price/I like this product.

Very handy, used for testing water and oral PH to make better health choices. Loads of strips, will take a while yet to run out.
