Query: Powerful driver

I have been using this driver for about 1 1/2 years and still on the original 2 batteries that it came with. I picked up an adapter set so I can fasten socket head cap screws. I use it primarily for driving bolts, 4mm to 10mm snug then I torque with a torque wrench. I also use it for electrical terminal block connections thanks to the variable torque settings. This driver is tough! It has been submerged in hydraulic fluid, dropped from 10ft, dusted with metal grindings and it keeps on working. After the hydraulic fluid incident, I just sprayed WD-40 into the motor area and blow it with compressed air, good-to-go! This driver is small enough to fit in my travel tool case too. I was surprised how much torque it has and it also feels good in my hands. When it finally dies, I will be getting another one without a doubt!
