Gorilla-Tee™ is the only batting tee in the world covered by a Lifetime Guarantee. Each is built to last and to literally provide the owner with a lifetime of use and enjoyment. If something ever goes wrong, we will fix it, or replace it, and make it right. Forever. That’s our promise. Products covered by the Gorilla Guarantee include the professional model batting tees with model numbers GORT, GORTJR, and GORTRI. Each product comes with a detailed Owner’s Manual inside the box. The manual is filled with information on how to use and care for the tee. The Gorilla warranty is explained in detail – with a product registration card included – so that the owner can contact the Gorilla-Tee™ factory (not the dealer) should any warranty issue arise.
