It takes less than 15 seconds to empty my pouch. Emptying, cleaning, applying barrier ointment and hand washing all take only 5 minutes.
Since I use the barrier cream, I rarely get butt burn.
Control is not a big issue. For weeks after takedown, I did have incontinence while sleeping. I solved that with taking 2 Imodium before bed. (I still need to do that).
When my pouch needs to be emptied, I feel a subtle pressure on my anus. I can easily put off the need to empty for a couple of hours.
Passing gas is exactly the same as when I had a healthy colon.
