Product review (5 stars): Perfect Replacement knobs
Cheap plastic knobs that came standard on my 30" cooktop all broke or cracked on the stem within 2 years. Bought these for a replacement after calling Whirlpool and finding out they charged almost as much for 1 as it cost for 5 on Amazon. These are OEM just make sure it is the Cooktop you are buying these for. I see other reviews where people give this a negative review because it doesn't fit there stove.
