There is a Bosch air impact wrench I bought a long time at home which can’t be used, and I always wanted to buy a similar air impact wrench. So, on black friday, as the price was 1499 , I can save hundreds to buy it, so I bought this one. the wrench work fine, it use good material, the weight is just comfortable to handle, and super comfortable! the quality is good, especially the handle and the trigger connection combination, it is very easy to use. In addition, the display of real-time power is also very useful.
