The water test for PFAS was easy to do and the time to receive the kit and mail it back and to receive the results was very quick.

I felt timing was handled very well. I was a little confused with the verbage in the details section about the levels of toxicity.

The fact that your employee (Adam) is telling the customer's the truth about your product and not sugar-coating it with lies. Whenever a prospective customer is inquiring about your product features and what it is supposed to do relating to mitigating a contaminated private well with PFOS/PFOA/PFNA, etc., your employee (Adam) properly informs the prospective customer with facts.
