We’ve had this oven for a couple of weeks and have put it through some paces, except a full on holiday extravaganza. However, I fully expect it to meet whatever challenge I present to it. We love it. It cooks beautifully and looks great. This is our first convection oven, and it has been a delight. We have cooked with both ovens at varying temperatures with excellent results. The cooktop heats up quickly and consistently. It is easy to turn on the cooktop if the lock isn’t engaged, and it’s easy to engage it. It’s a safety feature I appreciate.
