This cooker looked ok online but when it was delivered we were very disappointed. It looked very cheap and when we took the shelves out of the oven there was a metal plate which you had to slide in between the grill and the control knobs every time you want to use the grill. There is nothing to secure it in place, so not permanent, but it is a heat shield for when you use the grill to protect the control knobs. Never heard of anything so ridiculous in my life. You then remove it when finished with the grill??
We sent this cooker back.
