Excellent packaging (cardboard box and a lot of foam inside) and shipped quickly. The assembly is very simple, the machine is robust and well calibrated. Once the bed (tray) is set, you are ready to print. Moreover, for beginners, there are better and faster than owls on the usb key to test the printer. "Bed leveling squares" to check your bed settings and "XYZ 20mm Calibration Cube" to more precisely check the axes of your printer are a way better and faster. I made about ten prints in PLA, with different shape, size, with and without support and everything went well. In a hurry to test with other materials. Last info, the additional "limit switch" is no longer provided in the accessories, apart from that everything is perfect.
I placed an order for the Mega Zero to be shipped from Spain to UK at the end of Nov last year with sellers guarantee of shipping within 5 days and on time delivery 15 days but I am sorry to say that they did not deliver on their promises and instead have offered me a substantially higher priced replacement at my own cost. Very very disappointed- Zero Stars.
