Convection Oven Reviews?

I had a great one by Farberware about 20 years ago. When it broke, I replaced it with the same model, which never worked too well. It would burn the food without cooking it all the way (and on "low" it didn't cook much at all).

I replaced it with a Bravetti Jet Air which has lasted barely one year before it stopped heating much (and it never got all that hot, either). I liked the idea of the Bravetti because it had an option to turn the air flow to: off, low, med or high, which would cut down on over browning before cooking all the way through the food.

I am looking to replace it (right now it's a glorified plate warmer).

Any suggestions?

Thanks,
