i have a hercules which i used fairly stedily for a few months, now use more sporadically, tho iv just told my gf i own one so intend to use it before sex sessions. iv found it does more for my girth than my length and that it has has a bigger impact on my soft cock than hard. in the tube i become v big, over 8 long and maybe 7 thick but it decreases when i pull out. my hard cock is def bigger tho for maybe a 24hour period after use, my soft tho has probably become longer on a permanant basis.
id say that you would immediately have gains of around 7 x 6.5 after your first use, just get to know how to build the pressure. pump slowly and start with a semi. for max results i pump for a couple of mins, get some good length then pump full pressure for 20min or so. that is when i get HUGE in girth
enjoy! you will feel great with the extra fatness and should receive comments from sexual partners and stares from gym members alike!!!
i got mine from a sex toys website in the uk, v fast delivery but i think you can now easily get it on amazon, e-bay etc. its becoming more common
