Product review (5 stars): It's glass....not sure I really "love" it.
Best glass ever...I may love it more than life itself.. Feel like breaking it so I can buy it again and again, I LOVE it that much. It works. It fits. I don't love buying expensive pieces of glass.

Be sure to check your part number before you buy any parts for anything. I bought it from the Marketplace but it came direct from Whirlpool very quickly.
