GE Sensi-temp burner (electric range)
The GE Sensi-temp burners were a nightmare. Did you ever try to cook on one? Hot, cold, hot, cold, hot... oops burn't the butter! The sensor was unavailable from GE since who knows when. Our 1956 dual-oven range was georgous and functional, but we rarely used the Sensi-temp burner, and it was one of the 2 large burners. The P-7 self-cleaning 30" range that replaced it was nice, but the self-cleaning wasn't worth it, Mom realized that I was right, we should have kept the old one (Almost the same range that Unimatic has).
Finally, in the 80s I guess, GE did away with the thermostatically controlled burner, but too late, the ranges were all junk by then anyway.
If I had that range today, I'd convert that miserable burner to a regular Calrod somehow.

Electric cooking is wonderfull, just make sure your pots have flat bottoms and don't rock on the burner.
