I think you're right! But given that "the fan is a low noise 26.5cfm 60x20mm", who really cares?
There's no way it can perform significantly better than the one in the review.
It's simply a very, very bad product! It's more of an example of what people will do for a buck. Note how it's sold on consignment only: if the word gets around, no one will buy it, and the orders will be cancelled.
