I agree with temp. If you can afford [words=http://www.phallosan.com/shop/catalog/default.php?z=eNortjIxtVKyL0pNszWxMFcrSSxKTy2JL0hMT7U1UisoykyxtbBQSy4tLsnPjS8uKcrMS7dVsgZcMMpbEbo%2C]phallosan[/words], than buy it. After you get used to it you can wear almost all the time. I used to get about 15-16 hours of extending a day. No other device that I know of can give you that much. But remember to slowly work up to it, don't just jump in full force. I did and got a blister. Ouch.
