Ratings disagree by 8 steps

The engine rates this unit higher than the imported list, usually because the list de-tiers units that lack independent testing while the engine records that as low confidence instead.

Most likely for the Asian market; sightings in China and India. Ketchup and mustard cables, different fan grille, label, and box.
