If they do not package it very, very carefully and the mail guy throws it in the bin on his truck, you just bought a new nothing.
These elements can die just from improper storage, they are very very fragile.
If you want a NEW better replacement, look for RB Micro online, they have a very nice replacement for the D104`s that is not 20+ years old, cost`s about $30 bucks and the element comes pre wired so you do not even have to apply heat to the back of the element..
they even offer a warranty, The Guy on E-Bay spends more time and words saying
If you BUY it YOU bought it to bad so sad sold as is no refund
than he does anything else.
