The pretty design and marketing were pretty much the only distinguishing factors for the R2/C2 series (I hear the R1 was a better machine at the time). They're decent enough machines if you modify them enough, but they were marketed as out of the box ready for noobs. And they were not. Faulty beds with faulty connections, poorly packaged printers that broke themselves on transport, ridiculously noisy power supplies... At least for the initial batches there were large numbers of duds, including as mentioned some sent to YouTube reviewers (multiple times). And even today, the machines require mods to have proper cooling, both hotend and part. Stock machines clog with e.g. ColorFabb PLA/PHA because of the tiny, incorrectly mounted hotend cooling fan they ship with, and the part cooling fans need to be modded to actually point at the part. And software wise it's even worse. Ridiculous changes to firmware that add broken versions of already existing functionality, an OS that's a collection of stuff they threw at the wall until part of it stuck, and RoboLCD code that's unsalvageable and of dubious reusability anyway because of licensing issues. I'm not surprised they're going out of business, as their product had a lot of flaws that they never truly fixed, even though the community repeatedly asked them to and offered advice on how to do it. It sucks for us as owners, but we can always mod the machines with better, industry standard parts as things stop working. That will make them better, anyway. At least the mechanics and assembly seem to be pretty sturdy for the most part!
