The G Tee is the best tee that is available period. I've used the same tees and attachments going on 5 years now! I personally love the low ball attachments because you can practice hitting pitches that are actually being thrown in the games. Learning to use your legs and attack low pitches improved my hitting drastically. These attachments are not offered on any other tee. If you are looking for a tee that is approved and used by professionals look no further, the G Tee is for you!
