First, i own one.. and im very picky...
1. Quality is STUNNING. here is a fly fishing reel (not my design, thanks michael) at .1mm layers, with translucent PLA.


2. Ease of setup - within 20 minutes you are printing... Its generally a leveled bed right out of the box..
3. Dual extruders, and direct drive (so you can print flexibile materials).
4. Cover for printing ABS without warping.
5. Support - tang from FF support is responsive and good. I had 1 issue (my own fault) and he fixed it immediately.

Ive had no real issues to speak of.. its running right now... i just think its an amazing box.
