I bought this gun thinking that it would live up above that I could use my batteries 10.8V with it. When I received the box I immediately felt the weight of the beast and when I took over I said to myself: it will not do it! This tool is great for no reason. I do not understand how they did it to implement such an enormous engine to a tool of 10.8 V. Even my little wrench 10.8 V Metabo is not as heavy. The tube also quite heavy, to wonder why. They could have done a tool with a lightweight aluminum tube and a much smaller motor. The irony is that the free version contains batteries "NO" accessory unlike Milwaukee Makita models (which are much more versatile, from the videos). So I opted for a Cox Airflow Combi Compact III (air gun). A wonder = light, versatile and cheaper. It's very disappointing from Metabo !!!
