Ann: New Distributor Expands Robo into the Middle East, page-4

I'm not sure on this one, I'm a newbie with 3D printers but doing a bit of googling there seems to be a lot of different 3D printers (massive competition and continual technology advancement) which brings me to the question of if R2 will be popular? I've read some reviews on the R2 and they have been mixed so its not as if it's a great printer, seems okay at best. That goes for the rest of the line up. While it seems to be growing and sales are increasing (albeit off a low base) what will make this a long term winner? What will it differentiate from others?
