This is our 2nd GE 240 Advantium. Our 1st one lasted us over 17 years and my wife will not cook using anything else because nothing is as efficient as the Advantium. It cuts cooking time down to about 1/3 of normal ovens and the prepared dish is always moist and tastes great. We highly recommend the Advantium to anyone who dislikes being in the kitchen. It is by far, the best appliance we have ever owned.
