The kits for testing PFAS were really easy to use. The video online was clear and easy to follow, the kits arrived quickly, the tests were easy to conduct, and the return shipping was also straightforward. The test reports were clear and informative.

I appreciate how quickly I received my test kit and how quickly the results came back. I was lucky no PFAS were found.
