Had this tool for 4 years and LOVE IT
5 Stars
Had this tool for 4 years and LOVE IT
This is one power tool that I’ve never regretted purchasing and use ALL the time! It works so well and the strength of the turn doesn’t change if I put on extenders or those sleeves to bring it to 3/8ths or 1/4th! I’ve used it for things I never imagined I would use it for! The battery charger broke down on me year 3 so I purchased a cheap Chinese knockoff that charges even faster! The battery life i would say realistically is about an hour and a half to 2 hours of constant use. I wouldn’t recommend getting the set with the Milwaukee branded charger. (Check out photos for the better and cheaper charger than going with the set) Also, be aware that this is not an impact ratchet! Some people have written on here that it has weak torque because it couldn’t remove their tire bolts! Derp. So yes, there will be times you will have to loosen some bolts on your own and remember that manufacturers often use loctite on bolts making them even harder to remove. Once you get a bolt just a bit loose though you can just transfer the bit in 2 seconds and press the button. It saves time still! I’d expect to have to manually loosen rotors, oil drain plugs, and tire bolts.
