After the second time dumping my crockpot while taking food to a potluck, I searched Amazon for a lockable lid for my crockpot. I was unsuccessful, but I did find the Lid Latch. It was instantly clear that this was a great purchase, and I've had friends purchase them since.The Lid Latch is versatile and can accommodate many sizes of crackpots and casserole dishes. The package even came with two so that you can share or have a backup. This is a really great product and would make an excellent gift or stocking stuffer for the avid cook.Pros - the silicone stretches more than adequate to fit snuggly on most crock pots or casserole pans. - the silicone is non-slip and holds lids in to place and prevents leaks - there are multiple loops so that the desired level of snugness may be found - two to a package - seems quite durableCons - I do constantly worry that is going to rip or break at the wrong time and my food is going to go flying. It has yet to happen though.
