Rival 38651-C 6-Quart Slow Cooker

I bought this crockpot with confidence approximately two years ago. I figured Rival was a well known brand name, and my parents' crockpot has lasted over 30 years. I used it with no problems on an occasional basis (once a month, or so). After owning it for just under two years, the crockpot no longer heats up AT ALL. When the crockpot is set on high, there is NO heat after several hours. How disappointing, after owning it for less than two years.
I love the idea of crockpots and plan on buying another, but will likely not go "digital" this time. I will try one with an old-fashioned "Hi-Lo" knob, like the one my parents have owned since 1976, which still works.
