I have a dual flashforge 3d, from china, and it's excellent, 6 months+ down the track still loving it. The filament is hit and miss, the bright colours are great, black is hard to get a good quality from china, all the ones so far ive ordered from various suppliers are rubbish filament - but thats just the black, no other colour ive had problems with. Even the cheap stuff, the white I buy for $20/1kg 1.75mm abs and its just great.
