I don't think that counts as a "test gear" (this particular subforum...) but, I guess someone will relocate this thread somewhere more appropriate.
Anyway, I happen to have similar one, and it is perhaps produced by multiple manufacturers... Mine is quite poor quality: the aluminum base has even a hole in it (still sturdy enough), the handles/lead screws have quite a bit of slack, the sliding has quite a bit of slack (this is possible to tighten up, but it is hard metal sliding against softer metal, so it has its limits), and IIRC, my setup was missing one advertised attachment part (no biggie, I would likely end up getting different items from shop anyway).
Still good enough for small hobby stuff.
Seems one can now get these for even cheaper than back then, and at the same time get more stuff with it.
