Breville Smart Ovens are great but also decidedly not buy it for life. Breville doesn't sell replacement parts, and they're impossible to disassemble for a full cleaning. Of the 5 my friends and family own, one died after about 7 years, another has a noisy fan, and two have control panel issues (buttons activating the wrong function). All of us who have them use them at least once a day every day. They're still a great product and one of the only kitchen gadgets I'm evangelical about, but not really BIFL.
