This oven appears to be of high quality. Performance so far has been excellent. Easy to use. Temperature appears to be even across the oven with no "hot spots". It is easier to program than I anticipated or am used to. I haven't used the self cleaning feature. The side opening door is a major plus. I loved my old oven and only bought this one over that brand because of the side opening door. So far this oven outperforms that one in cooking variables and ease of use, so I'm happy.
