Not to "poo poo" any above comments, but put a lot of thought into which device you buy. The BIB "starter" is my personal recommendation....but only because I've had excellent experiences with hanging, and with the man himself from a customer service standpoint. BIB has a no questions asked return/replacement policy. Early on when he was developing the "starter" and "starter, hardcore" (the starter w/out the gel cushion) I helped with testing, and when I had a crack, or something broke, I had a new hanger in a few days at no cost to me.
Hanging is not something to take lightly either. I highly rec. that you study up on all the sticky threads, and videos available here in the hanging forum. You also need TIME to devote to hanging. It's a worthwhile endeavor, I've gained about 2" of solid length over the last several years of on and off again hanging...but it is the most time consuming type of Penis Enlargement to engage in. I'm not knocking the Max Vac, or Grip, or other vacuum hangers either...but I've heard many complaints about blistering, and I've had blisters as well from using them. Blisters take time to heal from, and that keeps you from hanging consistently due to having to take time off every time you get one. Supposedly if you take the time to adapt to hanging with a vacuum hanger, you can eventually hang similar weight ranges as with a BIB hanger....but I did not have the patience to wait several months to reach that adaptation level. To each their own though. I'd personally rather be able to hang heavier weights for shorter time periods, at 15-20 minute intervals vs maybe a few pounds for several months while hopefully adapting to hanging under vacuum.
Just from my personal experiences. Again, study up on hanging before making your decision.
