Joe says: Operators are standing by!!
No operators are really involved in the process of purchasing one of these, but sadly the city of Houston is. Don't worry if you're too short to use the swing trainer, boys and girls- if additional height is needed, a platform could be used to raise the Swing Trainer. Thanks for the simultaneous advice and blowing off of a fairly legitimate concern, FAQs section of the website!
There's also some nifty photos of Joe showing off his Swing Trainer to a group of Texas baseball coaches. Yes, nifty is the right word to use when a 65 year old is swinging an aluminum bat.
