we got our son a set last christmas classic from one of the vendors. best purchase we ever made. on the rainy days when you cant do your sprints its great..small enough to fold and slide under the bed and easily pops out to work out infront of the tv… it does take getting used to but only like a day or 2 ..he even brings it to the nats for sunday early am warm up( no practice) to get the legs moving…
def recommend it. we have the alum ones very light wt and folds in half for storage… pretty cheap about $160+ tax i think… andy prob carries them or can order them for ya
