dinkydy, where you you get the genuine Kingston drive from? How do you know it is genuine?
Buying things like this on E bay is high risk, and the savings are really not worth it, when you can by the same thing from a UK retailer like Scan, Novatech, and other specialists within the UK where you are more likely to get what you ordered, and if you don't, it is easier to get redress.
Personally I tend to buy my USB sticks/CF/SD cards from 7day shop in Jersey, but there are lots of UK retailers - just Google 'flash memory' for them. Here is a selection:
