Quality Adapters.
Very nice 3/8 by quarter inch adapters. Bits push in easy and lock. 3/8 end goes in smooth

Stay away
I just got these, put each one on my Craftsman 3/8" square drive impact driver turned it upside down and both of them fell off without even pulling the trigger. There is .020" slop in the fit. Useless!

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 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

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.

Converted my 3/8" impact into a powerful 1/4" driver!
I ordered these specifically to use my 3/8" impact as a driver using 1/4" bits. Works very well. Looking forward to trying it on larger lag screws.
