0.1 mm layer test - the model is only 3.5 cm high. Pretty good I think. You can see on the photo with the hand, that my fingers have much less resolution than this model :-) Quality is on par with very expensive printers I think. $3000 Makerbot can't do much better, from what I've seen. And I built this one myself! And printed some upgrades. And modified, compiled and flashed firmware. A very satisfying feeling, much better than buying off-the-shelf model. A lot of tweaking though...
