I've just looked at the penext youtube video and it looks like you put a noose around the penis and then you put wrapping over the noose. If you are uncut wearing a noose is a pretty painful experience so even though the belt on the penext does look good because you should be able to wear it discreetly i think it will be painful to wear. Plus i've looked at there website and it says "product discontinued" so if you broke something on your penext you would't be able to get spares parts because it looks like the official penext company are now closed down.
I know the phalosan is £225 + P&P but it is very comfortable and you can quickly rack up the hours. I used to use an x4 extender and after an hour or so i was suffering in pain but as i type this i've been wearing my phallosan for almost 8 hours straight. Admittedly i'm desperate to go for a wee wee but i will hold on until i've completed 8 hours.
Plus when you recieve your phalosan you can then pick 3 free condoms to use with your phalosan and they usually cost £18 each. Plus the official phalosan rep (Julian) is a regular at pegym and everybody agrees he's the most helpful penis device rep to ever appear on any penis website. Usually reps are so argumentative but Julian is so helpful and friendly.
