Bought this appliance a little less than a month ago. The unit is larger inside than I thought, lots of space for most needs. I haven’t had any problems to date. I purchased (and recommend) a thermometer to place inside, as there is no temperature indicator in the unit or degree gradients on the control knob. The temperature seems to remain consistent with the position of the setting knob. I’m waiting to see what the difference in my electric bill will be.
