Heats very unevenly on our glass-top stove. Had a horrible time trying to cook pancakes, some were under-done, some burned. It's smaller than I expected -- it really only fits three or four pancakes at once (my old electric griddle easily fit six). I also don't like the extra maintenance requirements (wiping it down with oil after every wash). I do not recommend this griddle.
Output:
negative
