I bought this yesterday and already took it to work. The battery had been fully charged and the gun struggled to remove 100 ft/lbs torques lug nuts from numerous vehicles. I do believe in Dewalt and own one of their 3/8" impact. I've found this product to work just as, if not better than expected. Due to this, I am going to talk to the store which i bought it from and ask to swap. I hope this to be the singular product malfunction and not the product as a whole. I wish to post another review with better regards in the near future.

Awesome Impact for Almost Everything
Like others, since purchasing this impact, I have had no need to use my high-end air impact. There is plenty of power in this to perform any of the automotive tasks I would typically use the air impact for like removing lug nuts or engine/suspension/brake disassembly. Given the ample power, I am always surprised how long the battery lasts. I have never needed to change batteries in the middle of a project. For example, I used this the other day to swap out summer tires for snow tires on three vehicles. After all of that the batter was still basically above 2/3 state of charge.
The only point of contention I have with this impact, is that the forward/reverse button is too easy to bump. I frequently end up shifting it from reverse to forward when holding the impact, without intending to do so.

Glad I bought this ,originally skeptical that it would be as powerful as my air powered impact gun. To my surprise this thing is totally awesome and my air powered model hasn't seen the light of day since!

Hits hard, gun is tough! I thrash it!!
Bought this gun a year ago, use it daily as a heavy equipment mechanic, haven’t used my air impacts since, gun hits harder than my Snap-on impact, hits harder than my co workers Milwaukee, I treat this gun like a hunk of medal, throw it around, gets covered in oil and asphault often, still hits hard! Because of the reliability of this gun I bought the cordless grinder, drill, drill/driver, & shop vac, more tools to come!

I think the torque values are over rated . I have a Hilti wrench that is only 4 hundred some pounds of torque that takes off fasteners after a few hits that the Dewalt would not budge , being rated at at least twice the removal torque of the Hilti ......go figure
