Product review (5 stars): These make large pots easier on your stove.
I purchased two of these for both the large elements on my stove. They take slightly longer to heat up than my old coils, but once they are on for a minute or so they are great. I use them to boil up to 5 gallons of liquid at a time and they do a great job. They have a higher clearance and lift the large pots up of the stove. Definitely worth it if you can.
