I am very happy with my impact wrench purchase . I was borrowing my friends Milwaukee Impact wrench to help remove the rear differential fill plug (which i could not get to budge with a breaker bar). The Makita XWT08M packs a lot of torque. Care should be taken when removing rusted bolts, Tighten a little first before reversing out as the gun can and will break bolts if they are seized. So far so good using this tool. Ive never had to use the second battery since I use this only for high torque applications like taking off axle nuts, brake pad carrier bracket bolts, differential fill plugs, etc. it is heavy but for the torque output, its understandable.
Its been over two years since i purchased this tool on July 2016
Its still running strong. It will take axle nuts off with no problems. I recently use this for the replacing suspension components (struts, control arms, control arm linkages, wheel bearing hub assemblies) which helped remove a lot of large diameter bolts. Get a decent sent of impact sockets with these kits (wobbliers included) and the DIY job becomes that much easier
