    It actually plays my old home videos on a screen the size of a stamp. It's my desk's favorite object.

    The remote is absurd and I love it. Setup took five minutes and my clips looked crisp on that little screen.

    Build quality is unreal for something this small. Feels like a real gadget, not a toy — and it's made here.

    Gifted one to my brother and now the whole family wants one. Tiny, but seriously mighty.

    Battery lasts through a work day on my shelf and the fireplace loop is weirdly cozy. Zero regrets.

    Loading my own videos over USB was dead simple. It's the best desk conversation-starter I own.
