Product review (5 stars): Waiting to replace ...heater element
I replaced the original WP heating element in 2005 with one purchased here on Amazon that was manufactured in Mexico for$60.
Its now 2014, 5 years later and the part from Mexico is still working (KNOCK WOOD). In advance of any issues I went ahead and purchased this one made in USA for $20 as a backup, when <IF>  The MEXICO one poops out..
  I see NO design change from the OEM part, NO change to heating coil, ONLY that the hole for a thermostat in the element slightly different...Which doesn't pertain to me since my OEM part didn't have this thermostat /overheat sensor anyhow. If yours has thermostat  I don't see the change in design of the thermostat hole on the side making a difference, you'll still be able to place the thermostat (overheat) switch on the unit. For the convenience of having a backup ....I like the $20 price...... Tumble on....
