Gator Grip Universal Socket

Down in the basement, the floor is a bit uneven due to the old floor drains, some cracks and just the general age of the entire place.  In order to properly put in the floors, I have to throw down quite a bit of self-leveling concrete.  The stuff comes in a 5 gallon bucket and you just add water and mix to get the consistency right.

The problem?  The instructions recommend that you use a 'mixer' - which is this metal thing that attaches to your hand-held drill.  Unfortunately, the mixer that Menards recommended requires a 1/2" chuck and my drill doesn't open up that wide.  So, what's the solution?  This thing above:  the Gator Grip.  It is perfect for this application - as it turns my simple drill into a socket that will hold the mixer stick.

It was $11.99 so hopefully I'll find more than just this one application.  The packaging calls out using it on stripped/rusty/broken nuts and bolts, so it might be good to have on hand.
