Has anyone tried using these devices? The Osto-EX-Vent made by KEM ENTERPRISES?
It looks like it helps to release the ballooning that many of us have issues with. It attaches to an ostomy pouch with a gas valve and for an ostomy product, it is honestly quite reasonably priced.
This is them and what they look like.
