Pros
Pro Fast and accurate
Pro Works after years and years of use
Cons
Con Software is not entirely clear, confusing between profiles, settings, and preferences
Con Lossless output not possible, nor is output sharp
Even at maximum resolution, the output is a bit blurry due to the fact that all output is compressed by JPEG. It is not possible to get lossless output. The best you can do is output at maximum resolution and then downscale to what you want.
