I purchased a ROBO3D R1, not as a backer but through their website a few months after the campaign completed. I didn't have a printer at the time so I wanted to buy one that was cheap but capable and had a good build volume. ROBO3D fit the bill with a $700 price tag and a build volume of ~8" cubed. The ROBO3D was by no means a plug and play machine, but I'm still very satisfied with it. I've had some issues with it but the forum on their website is very active and they're tech support is always willing to help out. The one thing I'm a bit disappointed in, is that they have continually upgraded the printer over the last few months. Since I've received the printer, they're replaced the Y axis slides with linear bearings, an easier bed leveling option and magnets to make the print bed removable. Even though i'm excited that they are continuing to improve the printer, I just wish that these features has come standard initially. But, all in all...great first printer.
