I was really excited when I received my new Vortex Plus! I loved it, however it soon started to have problems. I contacted customer service and let them know that the temperature was dropping by 5 degrees at a time while cooking. They were very helpful and replaced my unit. Sadly, the second unit it a lemon too! This units door does not close completely causing stem on the control panel, in turn causing the buttons to not work. Also,it shuts off randomly while cooking. Finally, the light works when it wants too. I'm disappointed and at this point just want my money back.
