I bought this lid because the other glass lids I own do not fit securely on my Instant Pot. Guess what? This lid does fit snugly down on my Instant Pot either. It just sits on the top of the pot and slides out of place at the slightest touch. Save your money; just use what you already have on hand. This lid is nothing special. I only gave it three stars for durability because I'm pretty sure it will get knocked down and broken before long.
