super quality, no wobble at all, I would say precision +-0.02mm awesome buyer, can only recommend, best seller with CNC components in China!!!
After cleaning, quality looks very good. Slide blocks are MUCH heavier than anticipated - ~200grams each! Should have bought the minis. Will re-configure my project to adapt. Lube fitting different than shown - comes with needle-oiler (see my photo)Shipping took forever, likely due to COVID measures. Very well packed.
