The seller is a middle-man. He buys and then resells. That he has good reviews for selling / delivering an item does not mean the item he is selling was not stolen at some time in the past. His purchase history indicates he rarely / never buys from the same source more than once and mostly sells used and parted out items.... a functional PW1 that cannot be registered for $39 dollars? No, I'm not jealous...I'm ethical.
Enough said. Enjoy your PW.
