We do! Each board is inflated for 72 hours before it’s packaged. During this process, we check the board for leakage and make sure that no deflation has occurred during the test. This allows us to guarantee there are no leaks in the board’s construction and that valves are working properly before your board hits the water. If you believe your board was received with a manufacturer defect, please contact us ASAP! Email us at team@retrospec.com or give us a call at (888)-488-2369.
