If this is replacing your existing (burned-out) heating element, be sure to keep (and re-use) the thermostat.  That little item is not included with this heating element.  The thermostat from your old heating element is still perfectly functional.  The hardest part of replacing this item for me was just moving the dryer away from the wall.  The part replacement itself was relatively simple.

Run the dryer once on high temperature to ensure it's working before you put the whole thing back together, and also to "burn in" the element.  Sometimes the first time or two can produce a smell.  You don't want your clothes to inherit that smell.  I took a picture of the heating element as I ran my burn-in cycle.
