## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent product!
*by F***N on March 23, 2018*

When I bought the Zero Water filter and pitcher last year, I bought the tester that just flashed red if the water was not pure. But I wanted an exact readingr and could not be more pleased with this one, which features a digital readout -- both Zero Water testers. With the digital meter, before I filtered my tap water through the Zero Water filter, the reading showed 207 ppm of dissolved solids. When I tested it with my new meter after being filtered, it read ZERO. I sure save a huge amount of money not buying bottled water!

### ⭐⭐⭐⭐⭐ Very nice meter
*by S***H on October 29, 2017*

This was an excellent replacement for the zero water meter. It reads the same, and very simple to use. When it reads 006, it is time to change the water filter. I am very satisfied with this product, and highly recommend it. Also the price is nice.

### ⭐⭐⭐⭐ SIMPLE & USEFUL
*by E***T on July 12, 2017*

This TDS tester is easy to use and provides useful readings. Although I cannot verify the accuracy of any particular reading I tend to think it's reliable because I've tested several types of drinking water (tap water, spring water, flavored water with known mineral additives) and the comparative readings make lots of sense. Readings do seem to be affected by changes in water temperature. Auto shut-off protects battery life.
