Product review (5 stars): OEM Original Part for DE712-05
I got an OEM Whirlpool part for my Maytag DE712-05.  Installation is a little tricky.  I had an access door on the back of the dryer to thread the belt in the motor area.  I followed the instructions to rotate the dryer drum after installation to seat the belt in it's proper location.  After rotating the drum a few times the belt moved to near the metal guide bar and I had to adjust it on the pulley so it was clear of that piece.  If I had to do this without the access hole the belt would have shredded prematurely on the metal guide.  Hope that helps someone.

This belt is 100 inches and came in an OEM original part sealed bag.
