So far, so good. Without having a M608 side by side, appears the same. Set up is easy even though the manual isn't extremely clear. On board micro SD card print of the four leaf clover turned out great. Currently running another test print before moving to larger jobs.
So far, there is only one drawback. The rear knobs to level the bed are tough to get to. Overall, leveling was not difficult first by eyeball to raise the bed to meet the nozzle then the sheet paper at four points. The dead center isn't as high with the four points scraping paper through. Time will tell.
