Mine arrived monday. Today will be my first day back at work since i got it. I will post a review, but what i can say so far is that the stroke variable is vast. it can go from very long to very short, keeping the same power. the voltage controls speed, so that is a constant. and the hit is firm. i mainly wanted it for a liner pushing large 14round shaders, 18 rounds, fat lines. I wanted something i could outline with large groupings fast, this seemed like a good answer because your hit is gonna be consistent, it has back off, and you can adjust the speed to run fast without increasing the force. so thats my thought, but once i saw how the long stroke at slightly slower speeds worked, I am thinking it can do it all...Maybe its time to post some pics. i guess ill read to see how to do that on here... ill post the first thing i do with this.
