Best out of several I've tried

Pros: These gaskets fit very snugly on the swingtop and I haven't had any bad ones yet. Best of all they have no odor which is better than some I bought from a local shop which smelled like rootbeer. Talk about a shock when I opened that IPA! And these are much lower priced, too, so I don't feel remorse if I have to donate a homebrew to a friend and never retrieve the bottle.

Cons: None
