I have had my pouch for just under two years and have had no real issues with it. I eat pretty much what I want to and have not experienced any adverse problems. I am over 60 and recently climbed the Mount Washington Summit. It took 5 hours and I did not need to empty my pouch until the end. I also ate and drank along the way. I did take two Lomotil just prior to hiking and made sure I emptied before I started. I would say that the only real problem I sometimes encounter is not being able to empty completely at times and leakage if I can't get to the bathroom right away. Other than that, I have no complaints. It is all individual, but most people do pretty well with their pouches. I consider any issues I might have as minor inconveniences.
