I have been coaching baseball since 1990 and directing camps and participating in camps since 1998. I have used many different types of batting tees over the those years and some are reliable for a period of time but there are none as durable and reliable as G Tee Batting Tees. I believe the integrity and durability of their product is a direct reflection of the integrity of the ownership and management of their company. They are always professional and responsive with getting you your orders in a timely manner. The warranty they provide also is another aspect of the integrity they have in standing behind the quality and durability of their product.
