As an avid user of Industrial and Scientific tools, I was truly impressed with the performance of this demo hammer. Based on my observations this tool delivers exceptional power that makes even the toughest demolition jobs easy and efficient. It’s comfortable TO hold and maneuver, and the trigger is responsive and reliable .The only drawback is that it is a bit heavy for prolonged use, but the power it delivers more than makes up for that. Overall, a great addition to any industrial toolkit..
