Courteous, friendly, helpful service and not just my own. I recently learned of another organization that sent its kits to an old address and Cyclopure replaced them. Michael Mullen Choctawhatchee Riverkeeper

Thanks for the feedback! We're glad your testing experience using the WTK went smoothly.
Everything was fine, easy to understand and affordable. I had some quotes from other labs that were more expensive but I doubt they would be any better.
