So just that you know I’m not trying to be a stick in the mud here. It’s just that I came across this brand twice, first time was about a year go on this YT video:
And the second time was your post about the wrench extender.
(The guys I linked above sure enough have a vid on that as well, I haven’t watched it yet.)
Mueller Kueps, by their own account, claim to sell to commercial shops, mechs, techs, (…) in the automotive field. And do private label for other well established brands.
They apparently have some Made in Germany stuff:

And of course the Allit boxes
Few online shops sell their tools, some ca be found on eBay.
I can’t speak for the commercial automotive repair world, but I can speak from a perspective as tool buyer and account holder with major industrial suppliers - if it wasn’t for that video and now your post, I wouldn’t even know the brand existed.
And everything that is not clearly labeled Made in Germany, seems to be the typical Taiwanese/Chinese private labeling stuff you can get from so many suppliers.
All I want to say, don’t pay top dollar prices for something that might be just the same tool that is available from other suppliers for less.
You will notice that the Mueller Kueps design
is offered from multiple other brands.
