Always good!
It's Milwaukee. Always good. I found Amazon is a good place to find Milwaukee tools and decent prices on batteries and chargers. A word of caution to those who don't already know you should never use those identical, off-brand chargers or batteries for charging or powering. Google it so you don't risk harming your valuable Milwaukee set up. ... show more

Came in a plastic bag
Product came working, but it arrived in a plastic bag with a sticker that said "new product" on the UPC. Pretty sure Milwaukee doesn't normally package their products this way, so it felt more like a "trust me, bro, it's new." This item was supposed to be a gift, so not great, but I did test the product and it arrived it working order. Batteries charged quick. They work in the Milwaukee jacket. ... show more
