OK, after my 4GB Play.com branded flash drive literally fell apart in my hands after one day I got on the phone to them and they found this alternative at the same price.
It is listed as Type C on Buffalo's site http://www.buffalo-technology.com/comparison-charts/flash-memory/flash-usb-drives/
Not sure how it compares to the other 4GB drives for R/W speed, but Buffalo are a pretty good make IMO.
