Looks cool. If this tool is designed to functionally add more mass to the socket and apply blows more evenly, I can definitely see this working. The only downside with this tool is half the time I pull out the air hammer, I'm air hammering at a slight angle.

I have the version that takes hex bits, and has an integrated handle. The bits are larger diameter than the common hex shank bits and are a little tough to find.

Worked to remove the rusted screws from my 36 Ford truck windshield frame.

I have both the 3/8" and 1/2" versions and definitely use the 3/8 the most, usually to break small things like a bleeder screw loose.. very useful.

Just bought one a month ago with 3/8 end for bleeder screws. Had a ujoint tool come in today. Have not had a opportunity to test either one yet. Just seemed that they would be handy.

I have the 3/8" version and the first time I really needed it I believe I got my money's worth out of it. Very rounded and very tight starter bolt on a front wheel drive Nissan. BEHIND the starter and access could hardly been worse.
After trying lots of things I got a rounded bolt socket, like one of these-

and used it with the Mayhew tool and an air hammer. Beat snot out of it which jammed the socket onto the bolt (finally!) and then a regular impact was able to knock the bolt loose.
The Mayhew helps break things loose here and there but isn't so great with regular bits and sockets. Often a hand impact is better for seized screws. You can hammer like nobody's business, but your twisting ability is limited. The vibration throws your wrench out of position too easily. BUT when you have something REALLY stripped and have such rounded bolt sockets that have to "bite into" the fastener to work, the combination is really impressive. So I don't use it much as designed but more to "set" other extraction tools. Not something I use much at all but a truly worthwhile weapon of last resort to have in the back of a drawer.
