I've received the item since 29 November. I installed it by myself, 7 days for installing (learning by doing). My big problem is calibration. I bought calibration clothes no.3 (4.4 M X 1.2 M). I have tried for more than 7 days but it was error. Until I checked the calibration clothes, I've got the wrong size (4.0 M X 1.2 M). So I've repaired the clothes, made them be 4.4 M X 1.2 M. Then calibrated again. Fantastic, success. Very good product. I'm so happy.
