So far, I am pleased with the unit. I’m particularly pleased with the fact I can fit 2 standard cookie sheets side by side. My previous oven (GE which lasted 24 years until it’s “Brain” died) was the same outer size but inner dimensions were smaller. A bonus! My only negatives are: it takes a longer time to come to temperature and (using a gauge) it’s cooler in its lower corners by a 100 degrees F, after the signal has indicated full temperature has been reached. I find wifi ability to be unnecessary...just a cute gimmick. I REALLY like the lower heating element is “invisible”...just hope it holds up as well as the prior one.
