Those complaining about lack of accuracy due to backlash (to the other reviewer complaining about hysteresis, this term is generally applied to magnetic fields while backlash is the correct term for mechanical systems), will need to spend at least double or more to get near zero backlash. For the purpose of routers or drill presses, you cannot beat this XY table for the price. I will probably buy another one to mount on my lathe. This is a beast of a table that is reasonably well made and achieves nearly industry level toughness, while not promising .001 accuracy that would be unreasonable in this price range.
