Well.. I would not buy any Wanhao printer.
They don't accept return by their policy even though the printer is defective:

Just to cite it in the policy "RETURNS/REFUNDS: Although we offer a 3 year warranty, there are no refunds or returns on any items purchased through www.wanhaousa.com unless it is due to a shipping/delivery related issue."
They say warranty, but they don't respond after they sell.
Don't buy a Wanhao. You will 100% regret.
