I have a variety of more toward contractor grade power tools from DeWalt, Milwaukee and Makita, all plug, and every one them performs as I would expect or better, never an issue.
On DeWalt, I have a sawzall, 4.5 inch grinder and drill. The former 2 are put through serious paces as I typically cut up at least 2 911's per year along with other various projects, and both are first quality tools.
Just ordered this, have 80 feet of tubing showing up on Tuesday. Research suggested that this Milwaukee model did beat DeWalt, Hitachi, Bosch, Makita, etc. on every spec.
