Product review (1 stars): I would not recommend these to anyone with children or small pets or LUNGS.
I don't think these burners can possibly be safe.  I ordered two of them back in early October because they were listed as genuine Whirlpool parts, however I do not think this can be true.  They give off an absolutely noxious odor when you turn them on higher than low to medium heat.  I have had to open my doors and windows to get the stink of these burners out of the house.  At first I thought there was some chemical residue or something on them from the manufacturing process, so I wiped them down very thoroughly multiple times, but the terrible noxious odor never went away, it happened every single time I turned them on over low/medium heat.  I don't turn them on high that often, and the smell isn't too bad at lower heat [but it is still discernible], so I thought perhaps it would lessen over time, but it hasn't.

I didn't realize when I bought these that this is a very cheap price for a burner element.  Now that I have had my eyes opened [and nostrils] as to the quality of these burners, I did a little more shopping around and found that these are about 1/3 the price of pretty much every other comparable burner element.  I got what I paid for, I guess, but I won't make that mistake again with my stove.

On the plus side, if you are on a diet, these will be a big help because you will certainly lose your appetite once you smell the reek from these burners.
