Okay, let me tell you....I purchased this for my fiance at a discounted rate in exchange for my honest and unbiased opinion. However since I am the female in the relationship, I gave it to my fiance to see how it compared to some of the other one's he has taken in the past. First off, in the beginning, it did not seem to do much for him, but since he has been taking these now for three weeks, both he and I can tell a difference. After the first week, he was going to give up on them, but didn't, and I was glad, for two different reasons. 1) Not being out of money, and 2) for the pleasure and satisfaction I got! Not only did it add inches as in size and girth to him, but his stamina was incredible. He wore me out, where as before I was always left hanging sorta-speak. As a blogger, both my fiance and I will be ordering more of the SizErect Ultra, as it does what it says it does. I don't now about most, but as a women looking at a men's perspective, I was impressed!
