Save money on the Milwaukee m12 kit. A few years ago on Black Friday I bought a Milwaukee m12 brush drill, impact tool, 2 x 1.5Ah batteries, 1 x 3Ah battery and a $100 charger. This set is half as good as the m12 tools. Rikon batteries lose performance when cold. A fully charged battery left in a truck at 20 degrees will only show one light on the battery gauge. At room temperature, they're good enough for small projects around the house.
