Rated 1.0 out of 5.0 by Cotton adapter unscrewed
I'm a sheet metal worker. i use these with my impact so i don't have to carry a drill and impact all day. i used mine about a week. like others have complained, the adapter unscrewed from the chuck when i tried to remove a bit. due to some internal ratcheting mechanism it's nearly impossible to remove the bit by gripping the chuck with two sets of pliers.
i can't belive they don't use a reverse thread screw to keep the adapter from backing out.
i exchanged it, hopefully I'll have better luck with the new one.
i had one made by jacobs that lasted about 15 years. so far i haven't found a suitable replacement. i tried two from the "green" home improvement store, $5.99 and $14.99 and both of those broke the very first hole i drilled.

Excellent product works on most of my old drill bits.

Rated 5.0 out of 5.0 by ParkPlusInc It works great
I use them from time to time. They work best with the Milwaukee bits that can take the impact of the driver. They are awesome for tearing through studs in the wall.

Rated 3.0 out of 5.0 by MADIYer Makita Chuck a bear but maybe worth the trouble
Like others here my Makita chuck froze with the first bit I put in. It installed nicely in my Milwaukee impact driver and I put in a bit according to directions. That went fine and a few test holes went beautifully but then I couldn't get the bit out of the chuck. It was frozen.
Very long story short: Repeated tries to loosed the bit by reversing the impact driver and holding the sleeve eventually unscrewed the shank from the base of the chuck! With the chuck off its shank and the bit still frozen I used open vice jaws to brace the sleeve while pounding down with a hammer, using an old driver bit as a punch, to force the bit out of the chuck from the inside.
After putting some WD40 inside the chuck to free the pawls I inserted a different bit but the chuck froze again! Reversing the impact driver only unscrewed the chuck shank again, so I cleaned white lubricant out of the threaded hole where the shank goes in and kept trying but eventually gave up in disgust.
I think letting it sit for a while was the trick. It gave the WD40 a chance to work. It not only loosened the pawls further, it worked as a solvent on the grease on the threads in the base of the chuck so I could clean more of it out. Threading the shank back into the chuck and tightening it on high torque, then at low torque reversing it while holding the sleeve and the bit dropped out. SInce then, though its only been a very short time, its worked as advertised.
I'm guessing this unit sat on a shelf in the warehouse for a long while and got gummed up. Some WD40 immediately after opening the package, an hour wait, then follow the directions on use and you MAY be in luck without all this (major) hassle.

I use my driver most of the time. It's lite weight and handy so when the chuck came along it was a natural for me. easy to store and you can always have a drill with carrying just one driver

Rated 2.0 out of 5.0 by Makita Worked for one time use, stuck to bit
I used this chuck to adapt to a Carbide bit, and it performed as expected. However, the chuck adapter is stuck to the drill bit and cannot be removed. I cannot find any installation instructions available online that can help me resolve this. If I used the drill bit on a daily basis, I would not mind this, but I bought the chuck adapter to add the needed flexibility to my makita impact drill for all my drilling needs

This allows my impact driver to be much more. eliminating the need to carry a drill driver as well.

Rated 3.0 out of 5.0 by semipro Seemed like a good idea
The chuck will not lock into my Dewalt impact driver, but it will lock into my Milwaukee impact driver. It will not tighten on a bit unless it is in an impact driver, in a non-impacting screwdriver it clicks and does not tighten down well. They do market it as an impact driver chuck, so that is fair enough, just something to note.
