Thank you for viewing. This product is palm-sized, very lightweight, and compact. Used about twice, with no scratches or dirt on the exterior. Operation has been confirmed. As an option, I will include a SONY external condenser microphone (stereo) set. By attaching this external microphone, it picks up a wide range of sounds clearly and without noise.
