Something tells me this is for 10U mostly. Or baseball.
I'm curious as to why you say that.
It appears to be a pretty good device for curing bat drag, and learning to keep the hands back, and stay connected. And, it teaches you how to move the bat with torso rotation instead of the arms.
$83 for just the device, is too much IMO I wouldn't buy it at that price. I'd pay $50.
P.S.
Duh! I just got it. Has to do with female anatomy.
Getting my now 9U daughter ready for the season. Will be updating this thread again. Have learned a lot reading lately. Need to get some current video of her swing. In the meantime, comments on this old swing appreciated. I want to use this as baseline. How is the swing plane? I know there is much to do on the stride.
