Glad I have it!
3 of 3 found this helpful Was shocked when I tested the first batch of colloidal silver I made before I got the tester! It tested at 4 ppm, rather than the 19+ ppm I had supposed. The second batch IS up to snuff! Thanks!

Very handy and easy to use.
What time I've been able to work in it, it has been easy to get around.
