I own a polaroid Polaprinter and am super happy with the result i find it is a more robust unit and compairing it to the vititar or daylabs there is much better colour , contrast and density rendition and also a much better sharpness. I use it to make polaroid prints, transfers and emulsion lifts in my lab.
if I need something of a much higher quality and image control I use my enlarger.
the results from being able to burn dodge and work the material is much superior.
hope this helps.
