Two AD300 Pro units, a BD-10 barn door, a honeycomb grid, and a set of 4-color gel filters are included. There are no malfunctions or repair history. Operation has been confirmed. There are no problems. The filters are unused. I've owned them for about a year, but the usage frequency was low, so I don't think the batteries have deteriorated much. •Notes One unit has a distortion in the aluminum reflector inside the front hood. (The unit in photos 12 and later) This does not affect shooting or operation at all. Removing the hood is also not a problem. Also, the charger and AD-E2 stand (light stand holder) are one set.
