Fuck! This CD player I bought off Ebay is jank.
While we were in china we went through this market and bought all these movies for $3. They're so jank, you can see the heads of the people in front of the camera at the theater moving at the bottom of the screen.
My parents made me call home to check in with them every hour.. it was so jank.
