Out of 80 random reviews:
Verified: 30 Good reviews and 27 bad reviews
Unverified: 15 good reviews and 8 bad reviews
It seems like the majority of unverified reviews are giving 5 stars ... Sony defense force?
Note: a good review is a 4 or 5 star and a bad review is a 1 or 2 star. (Strangely enough I did not ecounter a 3 star). I did not count 1 stars from people who complained about Amazon or 5 stars from people who haven't received the product yet (which was only 4 from the random reviews I chose).
