"There's always something new to be learned. I have been using Coloplast Sensura Mio Click (2 piece) without leakage problems for over a year. Well yesterday, a few minutes after I changed my bag I noticed the bag (pouch) was leaking from the bottom somewhere near the spigot. At first I thought I had left it unplugged but then I realized the bag itself was leaking. No big deal, as this is a two piece appliance I didn't have to mess with the barrier, only replace the bag itself, something I really like about the click system. But from now on I will pour some water in a new bag before I click it in place. I don't expect this to happen often but it my happen again. Just my two pennies for those of you using this kind of system. Happy bagging everyone!"
