The dcf895 isn't actually a 3-speed transmission. It just tones down the power and rpm of the tool electronically. So the first speed is equivalent to you only pushing the trigger about half way on the third speed. So if you have an application where your constantly twisting off heads or stripping them out, three speeds may be a good idea. Other than that this is a great deal. I bought three, kept one impact and all 6 batteries and sold the other 2 impacts as bare tool for $135, basically got 2 4.0 batteries and a charger for $100.
