Has anyone tried these please? They freely admit they're not quite as good as Hiwin, but how much worse are they I wonder??? And would it make a significant difference on a mid sized (1700 x 1220) gantry router built from extrusions, albeit very heavy ones.

He was not really positive.
I think he said it was still better then supported round rail.
