We guarantee our product to be free of product defect, under normal use, for as long as you own your trailer. Though we feel our customers will always be satisfied with our products, if anyone is ever dis-satisfied then simply return the product, within 30 days of purchase, and receive a full refund. Customers will have to pay the shipping & handling costs for the return. TGIG, Inc. can not be held responsible for boards damaged through improper installation, misuse or accidental damage.  Further, TGIG, Inc. can not recommend using our boards on surfaces other than "Factory Applied Finishes". Feel free to email us with any questions you may have about installation and use. NOTE: ALWAYS MAKE SURE YOUR BOAT REMAINS ATTACHED TO THE TRAILER UNTIL THE BOAT & TRAILER ARE IN A SUITABLE DEPTH OF WATER FOR LAUNCHING AND THEN UNHOOK THE WINCH. ALSO, ALWAYS MAKE CERTAIN THAT THE BOAT IS HOOKED TO THE TRAILER BEFORE PULLING IT OUT OF THE WATER. TGIG,Inc. recommends these launching and loading procedures for every boat trailer equiped with Ultimate Bunk Boards and does not endorse any other procedures.
