They tested our water after sending us the kit with thorough instructions. Our report came back in a couple of weeks with the good news that our water passed. Nothing to be done and no selling techniques used. Just a good report!!!!!!

Reasonable price, easy testing process, and we especially appreciated that our results were stated explicitly in the text of an email rather than needing to click on a link and/or create an account.
