Bought one a while back from woot. While it worked it was good. Unfortunately it spontaneously died one day. Woit took care of me, but I would not buy another refurb.
I bought a few of these. I have like 5 of them around my house. 3 of them were refurbished from woot. 1 came defective. Sounds distorted like a speaker is blown or something is loose inside. I just opened a ticket to ask for refund.
