Debbie Grossman from Popular Photography Magazine reviewed Nik Sharpener Pro 2.0. It can be summarized at follows :

“nik Sharpener Pro 2.0 is worlds ahead of its predecessor (1.0), with an easy-to-use interface and non-techie lingo that’s clear without being simplistic. It eliminates obfuscating terms like the aforementioned “radius” and “threshold,” and instead lets you adjust sharpness according to output, since different printer/paper combinations, print sizes, and probable viewing distances require different amounts of sharpening. Fill in those factors, and the plug-in determines how sharp your picture should be.

On-screen, though, your pre-output image looks like a poster child for everything Pop Photo warned you about: the grain is speckly, there are halos this way and that—it all seems sharpened to a crisp. But keep your mouse off that Fade command, because when you print, you’ll get just the right amount of sharpness.”
