There were no surprises with the flash drive. I bought it solely for the unique packaging. My one concern is for the USB connection. It is pretty thin, and I worry about its' long term reliability, but time will tell. That is the only reason for the "4" rating.
As far as the vendor is concerned, I have used BuyDig over the last several years. In all cases the service was on time, and delivered exactly as was advertised. No complaints here
