I looked at the ingredients, they are the same as those found in nearly all "Penis enlargement" pills. Even if a patch improves the body's absroption of the herbs all they do is stimulate the blood circulation to the penis. They do not create the conditions that your body had when it grew as a teenager!
I have tried a few brands of penis pills and never achieved what was promised on the websites but did notice harder erections. Since then I have created my own tea cocktail which is MORE effective* than pills and probably those patches since liquids are more completely absorbed by the body:
100% Gingko biloba tea, 100% Korean Ginseng tea, 100% Ginger tea, Circulation tea (usually for women with "heavy legs"), Body breakthrough - Yohimbe Edge tea that contains Yohimbe, sasparilla, avena sativa and muira-pauma.
I put all 5 teabags in a mug of boiling water and leave to brew for 10 mins, 30 minutes before PE for rock hard erections which are good for the "squeeze" exercises. A small amount of spirits like rum or whisky help with the awful taste and the vasodilation.
*for increasing hardness to optimise certain PE exercises.
