Query: buy this!

I had my first Nesco roaster for 18 years before I broke the glass lid. Now the lids are metal thank goodness. This cooker allows you to roast chicken, cook over a gallon of chili or soup and then vary the temp to perfection unlike the slow cookers with low or high only. We have several for our big get-togethers and it keeps me out of the kitchen trying to keep the food warmed up but not burned. Before use you MUST turn it on to "cure". I do it outside on the covered porch. No other crockpot compares. My friends and family all buy this one after they see mine. One of the FEW things I've bought that exceeded my expectations. Greatest wedding gift I got and give to others.
