I recieved a sample of the AlphaDry system, and I have to say I am
impressed. It is an external catheter type system, but with a resevoir
and drain valve built in so you don't need clumsy leg bags and such.

It took probably two hours for me to get comfortable with having the
device on, and it does feel a little weird as the resivoir starts to
fill (like having a baloon in your underwear. But it is very discreet
and kept me dry all day with regular draining (every 2-3 hours, about
as often as 'normal people' use the rest room.)

I still wear diapers at night to give my penis a break from the condom,
but it's nice to have a diaper-free solution for daytime use, that can
also be worn at the gym, in a pool, etc. I can wear shorts again!

As a backup, I wore a diaper over the device until I felt sure it
wouldn't leak.
