@piki I also use SkinTtac which I really like I never use a belt I use a coloplast one piece disposable system which I love I did get to see a stoma nurse at Mayo She told me that if you do not have some air in your ostomy bag it will pancake I also find I need to keep my stools very soft not to have a blow out This info has worked well for me in controlling leakage I also find the less products I use the better off I am I only use stoma powder if my skin feels sensitive which is rare. I gave up using the rings since they never seem to help I will use Skin Tac The stoma nurse did suggest putting the blue stickers that come with bags over filter of bags I do use a hairdryer to warm the ostomy bags and dry skin I have my changes of ostomy bags down to 5-7 minutes and its working fine for me. Everyone has to find what works best for them. I did have a nurse and coloplast tell me that with their product you do not need a barrier spray since it is built into their products but it does not hurt to use it them I also buy precut ostomy bags which works great I am 86 with bad arthritis in hand so I cannot cut my own bags
