I ordered a replacement dual element switch for my Whirlpool electric range on Friday afternoon before 6pm with regular shipping. The part arrived the following day (Saturday) approximately at Noon. I replaced the switch and the burner now worked properly. It took me 15 to 20 minutes from start to finish to make this simple repair. I was impressed with the quick delivery of my order. Thanks to all involved at Appliance Pro. I will definitely do all my future shopping at this site.
