Product review (5 stars): Easy replacement!
Great product, easy to install!  2nd one in 4 years.  We wash about 6-8 loads/week. Had this item for a year and it is still heating like new!  Approx. $20 to replace vs. $100's for a new dryer..a no brainer.  They only tend to last about 2 years for me, but at $10/yr. it is still a bargain.
