Of course it is the initial kick I watch, not the recoil as it resets itself. Having said that, I have not used the 3M model, just the Progressive and the Armada. Hope that helps. Disclaimer - Yes, I am a manufacturer but hopefully that doesn't disqualify my experience. Just trying to help. I do say that experienced contractors know more than manufacturers as they live it day after day. A lot of times, we regurgitate it, but not always.
Thanks, I'll give this method a shot
