Product review (5 stars): Great! Very inexpensive and saved me from paying for a repair service or new dryer.
After a little internet research, I learned these two coils were the most likely cause of my dryer not staying hot during the full cycle.  Am amazed at how inexpensive these parts were delivered!  Delivery was by USPS and well worth a few days wait.  Took me about 1 hour to open up the dryer, remove the drum, replace the coils (just two screws hold them in), reassemble everything and test that they worked.  Fairly easy job even for first time doing it.
