I never store what I cook in the Instant Pot in its inner steel pot with this lid on it. Too large for the refrigerator, I just transfer left overs to normal food storage containers of the proper size for what I need to store. Plus I use the IP a lot, so I constantly need a clean inner steel pot, and that is why I have two inner pots (highly recommend having two inner pots! Very convenient!). Thus, I never used this Silicone Lid, should not have bought it. Actually, should have returned it, but didn't.
