They've got three main shortcomings Four. They can cause fires. Consumer Reports this month had a recall of two brands that would catch fire. I have had several (not of the bad brands) do weird things when they burn out. In each case, they "smoked". It was unsettling, because I didn't know if the type of event could have led to a fire. Now I know.
