Harbor Freight offers two versions of Universal Impact Joint Sets. The
first style, Item 67986 I am familiar with. Been using that style for
years in my hand sets. The second one, Item 67920 I am not. Any
advantages to the second version. Stronger, work better, horror
stories...

I would NOT use this on an impact wrench. Too dangerous.
If you accidentally pull the trigger without the socket on a bolt, the
socket will fly off. Also they will go to about 90 deg. camming the
socket off the bolt.
You have to hold the socket to keep it on the bolt, your hands won't
like it :-).

Appreciate the warning/opinion but you're about ~35 years too late. I
used to spin roller bearings on my finger with the air hose too... still
have a small scar on my finger from that ;-)

Lucky that's all you have.
I built a little demo box for that, very effective.
When you tell someone, not to do something, you know that is the first
thing they are going to do.

I've used this style on impacts before (all those years ago). You lose
a lot of the impact torque, but they do work and can solve some tricky
problems. A few reviews on the HF page say the above model holds up
pretty well but they don't have any comments on the other version,
which I have zero experience with.

I'll probably get one of the three items, maybe two. I really like
wobble extensions, but the angle of attack is quite a bit less.

I have been using an impact for 60 yrs. and never used a 3 piece
universal.
You might check how many other tool mfg. offer 3 piece impact universal.
I don't think there are many.
