I bought an HD enclosure, and the fan didn't work, I contacted them via their premium phone number and never got a response, sometimes waiting for 20 minutes, I sent an email clearly stating the problem, they'd always reply with some mumbojumbo about the power supply, there was nothing wrong with the power supply and I don't see how it could affect the fan, in the end they didn't even reply to my emails. I would never buy anything else from these people.
