  • Yup, it's a keeper!
I like it! Very nice not having to look for power and putting up being tethered to an electrical cord on the job site. So far have just used this cutting rolled aluminum stock, .012" thick (not sure what gauge that is) and a little bit of ripping vinyl siding panels. Works great! Very accurate and easy to control. The variable speed is a nice feature. Much prefer the scissor type shears to the nibbler type that leaves and 1/4" ribbon. The shears does leave a little bit of a wavy edge but I've been able to control that somewhat by keeping the speed up, not pushing too hard, keeping the shears perpendicular to the stock, and keeping the stock well supported. Not too objectionable unless you need a pristine finished edge. Haven't done much curved cuts but I can see the advantage. The tool is very manageable and not too heavy. ... show more
