Product review (5 stars): Just as good as the OEM part for a much better price.
Why does Whirlpool price this element so high when it's essentially the same as the 3387747 with less metal?  I've bought and installed three of these Napco elements in the last year for my customers.  Each one I test fired on my bench to check for hot spots and  amperage draw.  All three tested excellent. All three of the installs are still working perfectly, several months later.  I will update my review if I ever find a problem with any of my installs.
