http://www.verticaljumping.com/nike_plus_basketball.htmlAny body thinking about getting them? Do you think they are accurate enough for the purchase? I know on YouTube it measures dunker JusFly at 49.9 inches on one of his dunks. The reviews on YouTube just kinda review the shoe itself and not the sensors, but I think it would be worthwhile to know how high I'm jumping on any given dunk or layup especially in a game. Any opinions? Hopefully Jack Woodrup gets a pair and gives a great honest unbiased opinion like he always does...
