The PowerSpec Ultra is my first printer. I like that it has dual extruders and is completely encased. Out of the box it is very easy to print simple pieces. The included software, Powerprint, is very simple to use and has good presets. As soon as I assembled the printer, I printed a piece immediately with no tuning whatsoever (note: this is not a plug and play printer, more complex/smaller prints require tuning). There is very little customization of the print settings in Powerprint so I switched to slic3r. Since slic3r does not include this printer in its presets, it was a bit tedious to get everything working okay.
The build quality of the printer initially seemed great, but now I hear some creaking during higher speed prints. This has not affected my print quality yet, but I am concerned about the plastic housing and other plastic parts. For the price I am satisfied.
