Are the Danby air conditioners as bad as the costco reviews say they are ?

I'm looking for an air conditioner and I saw on costco the danby ones. They look fine and exactly the specs I'm looking for, but the reviews are trashing them.

Reading older reddit threads about them, people seem to say they are great, and reviews on other websites also seem to say they are fine. Why are costco reviews so bad then ? I'm new to buying at costco, so I'm wondering if there is something I should know here... !
