Responding to a couple of @peterj116 questions:
I had glue for the incision in the crouch. It was a little scratchy, but each trip to the shower slowly wash it off.
Going on 3 years and about one pad per day, any leakage is usually when my bladder is somewhat full and, while sitting in a chair, lean over to tie a shoe. The device is designed to retain a certain fluid pressure and that squeezing action exceeds that design. That's a good thing to avoid urine backups or damaging the bladder, etc. The technical mathematics of you body's natural system and the AUS device can be found in the manufacturer's literature.
I hops this helps and puts you more at ease.
