Review on Comtim Pet Food Can Cover Silicone Can Lids: Universal Size for Dog and Cat Food - One Lid Fits 3 Standard Cans by Brianna Kamp

I have no idea why this product has so many good reviews. They are inconvenient to put on a standard jar, all different sized silicone rings are pressed tightly against each other so you press the lid onto the open jar until it sits in the ring and then you have to lift the jar and look under it. to make sure it is really tight or it will leak. It still drips sometimes when tipped over. Compare that to two cheap hard plastic caps that make a "click" sound when they snap open, you'll wear them for years, they don't leak at all, and they take a second to put on, no fuss to make sure they belong REALLY about it. I often use them for canning coconut milk and camping in a fridge full of half-melted ice, so they really shouldn't leak! I want more of this. That's not it. Don't buy them.
