For the 450 hz (450 turn per second) gyro the speed would be maximum 450 x 60 = 27000 rpm
I purchased the original designed nsd spinner made of hard good quality plastic and it exceeded my expectations by far and for only 28 dollars
I loved the original plastic version so much i decided to try this new nsd power ultimate winner's precision sterling spinner, gold and i was highly disappointed
Bottom line this spinner is made only to measure the speed at which you use the product and does not provide the resistance needed to strenghten your hand or arm
