I love them and put them on every pouch... even ones with filters as those often get clogged and stop releasing gas anyway. EZ Vents are very easy to attach, are secure and one can very discreetly empty gas from their pouch without the fear of leaks. I found burping from the ring or tail terrifying! You can use them with one-piece pouches too, even though the manual that comes with them only shows two-piece instructions. Just need to go through the hole you cut in the wafer.
