Rated 2 out of 5 by from Expected more from DeWalt than 2 weeks Bought this at the beginning of April to add to my battery tools at work (automotive). I use the red brand for most of my work but some tight spaces require a smaller profile impact. This one has the best torque ratings for its class so I was especially happy to have it in my arsenal. It gets much less use than my daily impact so I was very disappointed when barely 2 weeks in, the impact failed. I went to use it and when I squeezed the trigger, nothing happened. No forward or reverse. Tried the direction switch a few times but nothing. The LEDs and setting display both worked however the trigger did not. I have captured the problem on video, however, I can only post videos from YouTube, what's with that ?? I really want this impact to be better and am hoping it's just a bad unit and not something to expect from this tool. I will get it exchanged tomorrow and hope the next one lasts better than this one did.

Rated 5 out of 5 by from Awesome little impact This little gun whips off lug nuts in a snap and made doing tire change over so much faster. Getting a free battery made the purchase that much easier.

Rated 1 out of 5 by from Not impressed This wrench could not even crack a lug nut torqued to 100ftlbs. And barely tightened to 100 ftlbs. Tried every setting. Fully charged 4Ah battery.

Rated 5 out of 5 by from Très puissant et compact !! Je l'utilise principalement pour les roues de voiture. Je trouve que le nouveau Dewalt DCF921B est aussi puissant sinon plus que mon modèle à air tout en étant VRAIMENT compact !!! J'étais sceptique au départ, mais maintenant je suis convaincu qu'il peut faire le travail !

Rated 5 out of 5 by from Really strong. Super convenient Was really strong, will easily bust car or truck lugs. I used for a trailer which are 250lbs and it broke no problem. Putting back on I tightened with impact as well and finished with breaker which barely moved the nut.

Rated 5 out of 5 by from Awesome addition to our cordless tool collection! A cordless 1/2" drive impact has been on my list for awhile, since the majority of our cordless tools owned are Dewalt made only sense to stick with the brand. After a bit of researched we opted for the DCF921B super happy we did. After a bit of use found it to be extremely compact, lightweight (even w/5Ah battery), decently balanced, nice feature set in terms of control(s), smooth variable speed trigger, bight LED's w/three settings, and last but not least definitely powerful. Build quality is on par with what I expect from Dewalt so no complaints there. Love the "Precision Wrench Control" feature as it helps alleviate overtightening fasteners and that excessive spin after loosening a fastener... No stranger to this feature as the tools I use at my workplace, as a professional, incorporate similar technology coming in handy many a times. Price wise it was fairly reasonable... Was really hoping we could have found the "powerstack starter kit" deal (free battery/charger w/DCF921B purchase) but appears to be a USA deal only, as per usual us Canadian's gets left out in the cold once again LOL. Either way the DCF921B is a "highly recommended" from me.
