We had a GE Double Wall Oven in our house when we moved in 17 yrs ago. The oven was brown so I knew that meant it was old, like 1970's. I think this is one of the longest working ovens I've seen. So maybe 40-45 yrs old, WOW! The age of that oven and the fact that we have never had a problem in our 17 yrs of having it, meant that we were definitely shopping for another GE. Our new GE double Wall Oven arrived was installed and we are quite happy with it. It looks beautiful, it works great and I couldn't be happier. Thank you GE for making such a long lasting appliance.
