This kit is 100% functional. The battery does not take a full charge and will most likely need a re-cell. The cell is $77 via the Mack group. The pack was most likely a rental unit at some point. It has it's fair share of dents, dings and scratches but is fully operational. These things are tanks in case you are not aware. The heads were bought seperately and used sparingly....great condition. Charger, reflectors and plastic covers included. $2900 shipped with paypal personal.
