Summary: I'm a big fan of Milwaukee's M-18 tools - so much, in fact, that i sold or gave away the dozen+ Dewalt and Craftsman 18/19.2v tools that I had accumulated over the years. I have owned Milwaukee tools for over 40 years and, as with my experience with Bosch and Makita, always found them rugged and reliable. My experience over the past year with M-18 tools is consistent with my corded Milwaukee tools.
Summary: This tool is compact and powerful. The batteries hold up well and store lots of energy.:I had two compact 18v batteries drop out after about 1.5yrs of heavy professional use. Replaced without issue as a recognized bad lot of batteries. Problem free return. The belt clip and LED light are useful additions. Customer service has been great.The reps speak perfectly understandable English.Say what you will but not being able to easily converse with a service rep is terrible.
Summary: I was the last guy in the neighborhood to get a cordless impact driver and had to borrow my neighbor's every time I needed one. I've been watching the price on this at Amazon.com for a year and Twin Bargains had the lowest price I have seen right around the Christmas holidays so I decided to make my decision. It was shipped the next day and, after being delayed 2 days while in route in Ohio due to winter storms, it still arrived within the quoted shipping schedule.
Summary: Just got this bad bear and can sing its praise high enough. Milwaukee with its new M18 battery system has really hit it right in the nose. The built in light is a valued plus to the tool. The battery slides on and off easily, its well balanced, and very comfortable. High torque motor and current most power for this type of tool make me comfortable saying that the rest need to play catch up.
