Product review (1 stars): Poor Design
Installed 10-16 both arms have failed less than 6 months. Guide wheel will not roll and one come off and layed under heating element.  Cannot recommend the part. In addition, Pandora's OEM Appliance, the two parts purchased are not OEM design, China manufacture changed wheel design and they will not rotate after a couple of uses. Pandora's OEM warranty for only 30 days quick buck for them and the consumers gets screwed.
