Product review (2 stars): Not heavy duty
The size is fine, and plugging in is easy.  The problem that I'm experiencing is that the burner breaks off of the tripod and the tripod bends so that the burner sinks down into the spill pan. This is the second burner that I've had to replace for this reason.  I think that this is happening when I have my canner on the stove and the weight + prolonged heat causes the metal to heat up and bend.  Still, it seems that that shouldn't happen.
