Not sure which M12 model I have, It's 10 yrs old and gets used every single day in a dealership service department. Great for interior work, and just about anything held together with small screws or bolts. Smaller than a drill, but not as powerful as an impact.
The sockets also have a slight taper to them. They will go in and bottom out.
Less chance of rounding out the square hole, on the really tight/seized ones.
I have a Snap On soft blow. Works great for "tapping off" stuck wheels and rotors.
I do enjoy winding up like Tiger Woods and letting it rip on stuck alloy rims.

$10.00 dollars??? I have one from the mid 70's, worn but still works. Been sitting idle in the tool box for at least 15 years. Cordless 3/8 impacts have replaced it.
Guess I should put it up on e-bay. I was thinking of scrapping it.
Here at the GM dealer, fluid flushing is not recommended by the manufacture unless contaminated. Funny thing is after 3 yrs it turns a funky color and it has an odor to it. We try to sell a flush while doing a regular pad replacement if it's more than 50k or 3 yrs.
I do my own Honda every 2...

Further searching, this model # is not in the sears data base as far as what company made it...
