These guys ripped me off and have done the same to many others. They cashed my check and never completed the anlaysis of my samples. Then they have given me the runaround for over 6 weeks, refusing to submit a refund! I went to the BBB to complain and that's when I saw that they do this regularly. Take a look at Yelp or the Better Busines Bureau (where they have an F rating). When you are doing the search on either of these sites the name of the company is Pro-lab, Inc. Their address is 1675 N. Commerce Pkwy. Weston, FL 33326 Tel: (954) 384-****.
