Easy to use
I was very satisfied with the ease of handling the test kit. The instructions were very thorough, easy to send samples to lab. Extremely satisfied with contact system provided and updates received. Results were easily obtained. I did send  a question about further testing procedure with the whole house water filter system I had and quickly received an answer with complete explanation. So I was totally satisfied with the whole process and will definitely be doing another test in a year from my last results.
