I have had several printers the last year or so, and the Alunar Select Mini has impressed me the most. I have gone from a kit printer, to the Cube 3rd Gen to the M3D Micro to the Alunar select Mini.
My printer was crazzzyyyy out of level straight out of the box, but with about 5 minutes of calibration it has held level ever since. The only real problem I have experienced is one of the linear bearings for the Y axis was tightened down at a slight angle which cause the bed to bind. A removal of the bottom plate and some small adjustments solved that problem easily however and aside from a clogged extruder I have not had any other problems.
I have successfully printed PLA, ABS and wood based filament from this printer with great success. PLA at 195C, ABS at 230 and wood at 205 just FYI.
I highly recommend this printer to anyone looking for a small desktop machine!
