This worked fine. The driver loaded automatically on my Win 7 PC and the device works without problems. It's very light. Now I can easily have extra storage or transfer large files to/from my laptop or camera.
this is a great portable storage plus if you dont want to download stuff onto your PC you can just put it on your flash. the only bad thing is theres no little hook to put it on your keychain, and cap is not secured, so you will probably loose it in the few weeks :)
