2 known revisions of this model
Manufacturers revise a platform without changing the model name. Each row below is a distinct revision with its own rating.
Why this rating

Ratings disagree by 1 step
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.
