GLAD I didn't listen to the negative reviews! This lid is GREAT! I was skeptical but thought - oh if it doesn't fit my instapot 3qt - maybe it will fit on something else! WELL - it fits my instapot! It is a pliable heavy duty silicone - that you need to stretch somewhat to fit over the stainless steel insert that comes with the instapot. It is a very tight fit - but who wants it to be loose!? I've very happy that I purchased this - will be great for storing food/leftovers in the fridge. Highly recommend this item.
