Comes with what you see. Appears to be missing battery cover for a battery. Also no lens or eye piece. Powers on and turns on/off with av power (I just used a low voltage USB cord that won't be included). When on the device inside the glass vibrates and makes a noise.  I know nothing about these devices but I'm assuming they are finicky so please know you are buying this for parts and that its broken and needs repair. There are use marks with scuffing and scratches around the device. Please let me know if you have any questions.
