Its is a bit of a dilema...you could always just purchase both hahah! Like I said, maybe browse the forum, find some guys who have used the AutoSleeve because I cannot honestly tell you if it works or not. You need to wear the extender A MINIUMUM of 3 hours per day. During weekdays I wear mine 3-5 hours a day BUT HAVE ALSO incoroporated manual stretches AND jelqing into my routine. Feels super great man! Good luck, let us know what you decide to do!
