I bought a similar one at a similar price. Piece of junk. The bottom joint is loose and will not hold. Going to try putting a small jubilee clip on it to squeeze tighter.
Here it is

Is there any difference between the Noga-style indicator arm and the Manfrotto-copy 'magic arm' used in photography? Only thing I can see is the threads on the ends. An indicator holder is not too difficult to make - copy the gripping end of the one shown and put a flexure fine-adjust on the other as in Stefan Gotteswinter's design.

I doubt there is much difference. They all work in the same way. The manfrotto will have 1/4UNC thread
And a large array of prices..lol

In my experience the Chinese noga copies are very hit and miss. I think the issue with the ones I have is the steel balls, they aren't perfectly spherical. As a result they don't lock firmly. I have one from RDG that is really positive/solid, one from banggood that is hopeless and the longer katsu/aimtools one that is usable (but only just). The magnet on the Aim tools one is terrible considering it is twice the size of the RDG tools one.

It is probably more difficult in machining them to assure sphericity of a ball with a shaft coming out of it than of a simple sphere. I wonder if there is an opportunity to re-engineer them. Buy some bearing balls of the correct diameter (they will be good and round), drill them and loctite the old shaft into them.
The ball with attached threaded shaft will surely be available as a part from one of the industrial lego suppliers. So if the dimensions tie up, that might be an upgrade route.
It might also be worth looking at the other half of the joint. I guess it works by line contact. If the socket is not as good as it could be, that won't help things.

I'd not thought of that, ill measure them up and give that a go. Thanks for the suggestion.
Ive got a couple of cheap ones, they're ok for my purposes, you can increase the clamping force on the ball by fitting a thrust race under the tightening knob (if the spindle is long enough), just dont overtighten it or the internals can snap.
also the bases as supplied were linished so they were machined flat.
