The oven takes forever to heat to temperature.  Took over 15 minutes to get to 400.  Takes a very long time to cool down even with the door open and fan running.  The alarm beeping sound can barely be heard even when standing infront of it.  There's no point in having a timer if you can't hear it.  When baking cookies, I have to spin the cookie sheet because the one's in the back near the fan get browner faster.  It does however, do a decent job for the most part.
