3/8 adapter to 1/4 hex
Used this with my Milwaukee 3/8 impact. Worked great. Tough product. Fast shipping

Works as designed.
Nice tool chest addition.

Perfect for impact
I work as a tech and I use this all the time. At the beginning I was having trouble trying to put on the impact but now is like butter. Pretty easy to use and it holds the bits very well

Not for standard length bits
I purchased these to use with standard length 1/4" hex bits. They do not work for this application because the hole for the bits goes all the way through the adapter letting the bit slip inside the adapter.

As described
Good quality. Only issue is that they are a pretty loose fit on the 3/8” drive. It starts on but not as secure as I’d like.

Perfect fit for 1/2 inch impact
These were a great fit for my one 1/2 inch impact wrench. You will need to wiggle them a little bit to get them to fit over the hog ring...if you have that, but they are very sturdy and well built.

Meh
Not sure what the spring loaded tension is supposed to do. Doesn’t seem to do anything. The 3/8” socket female is very tight. The 1/4” socket side holds bits quite loosely. Paint is already chipping off spring end. Nothing special here at all.
