I've got an R1 + (new model). GREAT PRINTER for the price. I've had this one for about two months, ran a lot of stuff through it, and I've had only minimal problems. My biggest hassle was actually just getting the filament started in the extruder.

And I have switched out extruders and done some other not-so-necessary stuff to this printer already, but still I've yet to run into anything that really would have been any kind of deal breaker. It does help to have some 3d printer experience and be mechanically inclined, but this machine is just about as close to 'out-of-the-box' as you can get, and mine has been a treat.
As part of my beta testing I was sent a Mattercontrol Touch as well, so I thought I'd make a go of it and run the printer from either this or my laptop for the first few weeks, using the Mattercontrol software on both. I could have run Simplify3d, but I wanted to get a legit idea of how this hardware and software would work as delivered (and that was kind of part of my deal).
Soooooooo. The Mattercontrol Touch? I was done with this within a week. The Touch is essentially an android tablet running a streamlined app of the free-to-download Mattercontrol PC software, so you can run your printer standalone with this. First problem, the android tablet supplied is pretty cheap, like $45 Chinese knock-off cheap. So you are paying $300 for a $45 tablet with proprietary app software that is known to be glitchy and is still a work-in-progress. Does it have potential and will it likely get better? Sure. But you're still stuck with a cheap tablet, and for $300 you could go buy yourself an extra low-end computer and just dedicate that to your printer, or get one of the other stand-alone pieces out there with an SD card slot/etc. FYI, the app is NOT currently for sale anywhere by itself, that's their hook with the $300 price tag. I was willing to go out and buy a $300 tablet and run the app through that just to see if it was the tablet or the software causing the majority of issues, but that's a no-go until they offer the app separately.
So anyways, for the cost I would definitely recommend the Robo R1+. The print quality has been great for me, and you can't beat the reliability with the 8x9x10" build area for well under a grand.
