Product review (5 stars): Dryer Element
I don't normally review items, but there were so many negative reviews about similar products I thought I would put my two cents in.

My original element, in my Whirlpool Duet Dryer, lasted 7 years before it finally died.  I ordered the replacement Whirlpool 3387747 element.  I was not exactly the same part, the center metal bracket might have been a slightly thinner material.  However the part fit snugly in the housing and the one screw hole lined up perfectly.

The part is in the dryer and working fine.  This $20 fix was way cheaper than getting a new dryer.  Even if it fails in a year, it's still a way cheaper fix.  I'll try to remember to update this review 6 months down the line (it seems most of the existing complaints have the replacement element failing in the 2 to 4 month range).

But consider this, if it fails I will definitely come back and move the rating on this review down, so if this review is still standing as a 5, my element is probably still drying cloths effectively.
