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.

Works as designed.
Nice tool chest addition.

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

Why just offer to identical adapters?
The adapters were well fitting and well built absolutely no complaints about them. Some of the comments suggest otherwise, but they were wrong. By way of suggestion, I would have this to say since a person has little use for two identical adapters. It would make more sense if they offered one of them to fit a 3/8 device and one of them to fit 1/2 inch .
