Product review (5 stars): Do it right & $ave
The included over temp switch required drilling a new screw hole or reuse of old switch.  Housing should be supplied with proper hole. Easy to do, but.....
Easy install.  Be sure to open and clean the lint trap/blower duct and blower of lint or you may have an airflow restriction causing premature failure.  Check for blockage in all duct passages including exhaust (no kinks after sliding into final position).  If the door switch is broken be sure to replace it. Operation with the door open will kill the element by stopping airflow over the element. If the drum seals or rollers are bad, fix them.
Reviews claiming early failure/poor quality likely have an airflow problem. Bonus: good airflow = less energy, better drying, & long element life.
