People’s exhibit “A”:
Yes, I can see that the review is from 4 years ago, and apparently has been grandfathered in. (Though, as I recall, even 4 years ago Google had some way to filter reviews.)
Maybe the review is from a legit (but clueless) customer. Or from a guy who fell asleep on his keyboard and held down CTRL+V with his nose.
Still, in light of Google’s egregious mishandling of reviews, this is the sort of thing that makes you wish Google would just stop taking wild stabs at review-QC and just leave it to potential customers – humans – to make up their own minds.
