Makita lasted longer than my second marriage but finally gave up the ghost. I bought a new Hatachi 18 volt at Lowes that also came with an excellent flashlight that uses the same batteries.
The story is gun related! Be patient, sheesh...
Anyway, like every middle aged, homeowner, husband, father, new cordless drill owner, I was running around the house doing tons of little projects.
The daughter asks, "Dad, is something wrong with your finger?"
I immediately looked at the one with the hide scraped off from changing the battery in my van.
"No that one." pointing at my right index finger, my trigger finger, pointing straight along side the drill in stead of on the trigger.
I laughed and said, "Trigger discipline."
