I love that they're simple and very heat resistant. They didn't come with instructions to lock or unlock the hinge, but it's easy to figure out. Also, I'm not worried about breaking them at all because the material is pliable, but strong.
Moves large and small amounts of foods with equal ease. I lifted a whole pot roast from the browning pan to the crockpot with this tool. I also used it for moving around the small ingredients in a stir fry. Sturdy, but not bulky. One of the best kitchen tools ever.
