This device has been eye opening for me to say the least. After nearly 30 years of teaching, I'm still learning new things everyday with this awesome device.

The GOATs rotated their hands over extremely quickly as I have shown in previous GOAT Theory videos, but to actually feel it for myself?
WOW!
It feels wild to say the least to rotate my hands this quickly through impact.
