I my opinion, this is the best demo video they have done to date. Shows all the benefits and usability of this REALLY COOL tool! Got to believe it costs close to $2000 although Im sure it is NAINA. The ultimate drywall tool. Love how it uses suction to lighten the load. I always sand my walls prior to painting and repainting and normally use my old PorterCable 333 as it is so light. This new gizmo would be just the ticket for someone lazy like me as it would do a wall so much faster. I am amazed by the engineering that went into this tool combo. Those darn Germans.
