I personally wouldn't buy from him ever again due to my experience with him, and his very degrading manner and lack of customer service. But anyway, the product....
I got the 4 inch stp. For packing it's ok. I packed it down, as I hate packing "upwards" and I think packing downwards creates a more realistic and comfortable bulge. The shaft does get sort of square or flat when packing though, instead of holding its round shape. I know this is due to the shaft being hollow for peeing. It is what it is. This part sort of turned me off from packing with it because I didn't like the look it created in underwear but hey, unless people are staring at you in your underwear often it's probably fine.
Peeing: It didn't work for me, but may work for you. Different stps work for different people. At first it worked for me, but the more I tried to use it the more frustrated I got. I ended up peeing on myself many times, as I had to fiddle around with it to get it to cover just the right area. You may have better luck with it though, who knows.
