Seemed to work just fine
Didn't get 3rd party testing done to confirm but it came up as good and we have been drinking our well water without issues.

Would buy again
Seems to work and accurate. Water level wasn’t shown but goes to top of label.

Clean water
This kit was great and easy to use when we were testing our old well. I like how it changed colors and was easy to understand what that meant.

Simple way to test your well water for bacteria.
I tested our well water with this as it had a funny smell. It was positive for bacteria. We treated it using online information, and retested a few days letter and it was all better.

Gave False Positives - Tested 2 Times
Water sample failed test, went green at 48hrs. Took almost full 48hrs to indicate something. Did test #2 and same fail results. Concern grew and took samples to County lab. County's lab roanfull state tests with ecoli and got we back glowing results of no problems. State test fully was $135, would have been $35 for just ecoli.
