5 of 5 Great Customer Service July 6, 2026
Reviewer: Edward Stefik Owner EJS Great Lakes Dive Solutions from Lewiston, NY United States  
Excellent customer service from American Diver Supply! They were responsive, professional, and genuinely helpful throughout the process. As the owner of a service-disabled veteran-owned dive business, I especially appreciate supporting a women-owned business. It’s great to see small and minority-owned businesses supporting one another, especially within the dive industry. Thank you for the outstanding service—I look forward to doing business with you again!
