seriously. another video of a tool used in a way that it isn't meant to be used with adapters/fittings that aren't meant to be used
and you post these videos for what reason?
just like the hammer drill one, they aren't helpful, they don't show anything, nobody learns anything, if you are just throwing countless videos out there on youtube hoping to be some kind of youtube star, then you may want to find another outlet, tools aren't really your thing man.
i like to visit this thread because there are a few good tools and things you can buy at HF, get a good deal and still have a tool that does the job, even for professionals. but what is the point of buying every single thing you possibly can, wanting to do a review on it, but not using it for any intended purpose.
if you wanted to do a REAL review on an impact DRIVER (not wrench... use a damn impact wrench for lugs on a car, or anything over 100 ft lbs of torque required, you cant even change most lugs with a 1/4 pneumatic impact wrench which puts out over 100 ft/lbs because you need the extra force to break them loose in the first place) Then go ahead and get a 4x4, a box of deck screws, charge it up all the way. and drive deck screws until it won't drive anymore. tell everyone how many it was able to put down in one charge, how fast it put them down, and how fast the battery comes back to full on the charger. after that it's up to tool life in terms of useability of an impact driver.
even something as simple as making a plate with multiple bolts on it, torqued down in 10 lb increments and marked so you can go at the bolts (in a size that doesn't require a reducer), and see what the impact driver will take out in terms of bolts torqued to X ft/lb
