Works Okay
The chuck is nice quality for the price. It does however wobble a bit. Not the chuck holding the bit, but the design of the impact. The impact holds the chuck itself loosely. When you hold a screwdriver bit it will wobble or move a bit in the impact...well that will be the same for the chuck. It's not that bad. It just won't be as rigid as an actual drill. It works great in a pinch if you are only drilling a few holes. If you have a lot of holes to drill just use a normal drill.

Lighten your load!
This works great. Holds bits tighter than my drill does for sure! The best part it lightens my tool bag a lot because I can now take my bit drill out of the tool bag.

Good, but not great. Slips often
The instructions say to insert the bit, hold the chuck and then let it ratchet a few times when tightening. I did that, but the drill bit still likes to pop out anyway. Annoying, but not a deal breaker. I love being able to use any drill bit with my battery powered drill.

INFORMATION FOR PEOPLE GETTING BIT STUCK OR UNTHREATENING THE ARBOR.
INFORMATION FOR PEOPLE GETTING BIT STUCK OR UNTHREATENING THE ARBOR. So common sense would dictate this is obviously not a single solid cast or machined peace but rather multiple components assembled together to create a very handy keyless drill chuck that ready locks in to your impact driver. As such the arbor is threaded into the rear of the chuck that being said when used with an impact driver you can over tighten the locking ring of the chuck (black ring) to a point that it's tighter than the threads of the arbor that go into the rear of the chuck. Two simple FIXES! If you do manage to unthread the arbor simply apply a dab of red Loctite or even super glue or nail polish reinstall the arbor securely into the rear of the chuck then let it cure. Now use it as normal and get back to work. In the event that your chuck is still torque to a greater spec than you can manage to loosen with your attached impact driver just add leverage to solve your problem put a pipe wrench or channel locks or bench vise pretty much whatever you have handy on the silver forend and another pipe wrench or vise grips on the black ring turn the wrenchs opposite of each other to loosen the bit and now you're back in business simple fix no need to return it or assume you lost a drill bit to the cuck it's a very simple keyless chuck that plugs into an impact driver not much to it (same goes for the Dewalt or Makita version I use both) . Always remember the 10 percent rule! Ya gotta be 10 percent smarter than the tool your using.

Got to use it once....
Drill bIt is stuck in chuck. Does not want to release it. Purchased this for several reasons: 1) I did not have one and love tools; 2) needed to poke about 6 holes in a masonry wall to mount a TV on my rear patio and my drill is about dead but I have a couple impact drivers, this would allow me to mate them to the bit; 3) its a Dewalt and my tools are Dewalt, what could go wrong? The only redeeming thing is that it did the job very well. But now I can only use it with the drill bit that it is mated to. What is worse is that it is a borrowed drill bit from a neighbor. Now I need to go out and buy a drill bit to replace it. Justification for star ratings: Versatility - not very versatile if I can only use it with one drill bit (chuck will not release it). Value for money - not very valuable for the same reason as versatility. I had high hopes for this tool. Easy to use - it is very easy to use....as long as you have no plans with respect to versatility. I can not return since I can't get the drill bit out..... On a side note, if you need to drill a 3/8" diameter hole in a masonry wall and are in the Tampa Bay, FL area, let me know, I will let you use it.

Works Really Well on an Impact Drill
I just bought the Dewalt battery impact drill. I wanted the chuck to go with it for standard drills and holes saws. I went on line, found this, and bought it. I couldn't get it to work properly, so I read the directions. Please don't tell anybody. I learned that this chuck is designed specifically for an impact drill. I was trying to install bits like it was a conventional chuck. Turns out, the impact function of the drill activates the clamping mechanism in the chuck. It works really well! I recommend this.

Broke after a few uses, But Dewalt replaced under warranty
***UPDATE*** As a homeowner this initially was a nice accessory for the Dewalt cordless drill (which I do like, and use all the time.) This chuck just broke today. The steel shaft that inserts into the drill broke cleanly in half while I was drilling some wood. It failed right at the machined groove that retains it into the drill. Probably been used less than a dozen times, and wouldn't have expected such casual use to have it fail in exactly 5 months. UPDATE: I contacted Dewalt and they replaced the item under warranty. So, I'm glad for that. It does seem like a sturdy drill accessory. Maybe mine was just bad. If it hadn't broke, I'd give it 5 stars. I should add that Dewalt customer service was excellent.

Útil
Comprei a parafusadeira de impacto e várias brocas. Porém, não verifiquei se o encaixe das brocas e so percebi quando chegaram ambos que não batia. Esse adaptador serviu bem. Contudo, me parece que a broca fica meio frouxa. Não cheguei a testar na parede
