MTS - I think the product is more geared towards helping with hand/eye coordination. Woudn't you agree hitting a moving target helps improving h/e coordination more than a stationary one?
MTS can certainly answer for himself but my answer would be not like this.
Mark - I can't tell you how times I've seen umpires call strikes at the neck level! Maybe it's more with LL since they are volunteers, but even in the 50 games my daughter played in travel this year there were quite a few neck high strikes called - not consistently either.
I appreciate everyone's input so far - it's still something new for me and I haven't tested it yet to all it's advertised capabilities.
They higher in fp you go the less you see high zones. More importantly, as I think MTS noticed, it's either making a hash of this hitter's swing or it's reinforcing bad swing habits already there.
