It is in full working order with average signs of use (no deep scratches). Unfortunately, the off-camera/external battery cover snapped when I was testing it - but better it happened before sale.
I have tested it on camera (manual and TTL), off-camera (manual and TTL) and wireless - and it works correctly. This is one of numerous 5600HS/HVL-F56AM flashes I have, and I'm just thinning my collection as I tend to use studio flash more now. The pictures are of the item for sale - please ask if you would like to see any other angles.
