I am going to try this one more time. I have no idea why you keep rejecting my review.

I have two different 6 quart CrockPots with clamp-down lids. This model actually turns UP the heat when it switches to warm. Filled with water, it runs about 197 degrees after 6 hours on low, but when switched to warm, it heats up to 210 degrees within 1 to 2 hours, which causes the water to simmer. This would cause actual food to possibly be even hotter than this and probably burn, due to sugars and fats being able to heat hotter than water. For comparison, my other model, heats to 194 degrees on low, and 164 degrees on warm.
