Cold temperatures seem to affect my milwaukee batteries far more than dewalt. I prefer dewalt impact drivers and drills but milwaukee has a lot of sweet specialty tools. They seem to really cater to skilled trades. I've wired a lot of 500' poultry barns and made an interesting observation. There's a lot of screws in a metal roof that size. The dewalt guys would wear out dewalt impact drivers faster than the makita guys. I put up 2 for myself and out of 8 new impact drivers, 3 failed by the end of the second barn.
