Mine works great! I've never had any issues with it. Before I ever baked a baby, I put an oven thermometer in it and ran it several times to find out exactly what temp it needed to be set at to reach 265. After that, I just left the temp setting alone. I DO always bake with the oven thermometer in, just to be sure the temp stays accurate. I also always set the timer on my phone as well as the one on the oven, because the oven's timer is a dial and it's difficult to get it set for exactly 8 minutes. It's been a great oven, though. I've used it for about a year with no issues.
