Query: Can't trust the low setting.

I have had this crockpot for about 3 yrs. with problems on and off about burning my food. - figured it was my fault, because I wouldn't always have it 2/3 full even though I followed recipes exactly. I would always have to watch the food very carefully to watch for burning. I'm finally "throwing in the towel" and getting rid of it. Last week and yesterday, I caught my slow cooker burning my food on the "low setting"; the outside was very hot to touch. Yesterday, within 2 hrs of cooking, the liquid was boiling and the beans burning. Going to get a brand with better reviews and a smaller one in case that might be the problem.
