At first I was skeptical but I decided to try it anyway. I haven't purchased a license (yet) but even the demo features are impressive. It has a lot of functions, too many to list here, two of which that I don't already have are the bandwidth used monitor and duplicates finder. The interface is attractive and intuitive, and the price is a bargain. The two background process' do use a little bit of CPU and the main app a bit more but that's not too surprising given the number of things it's keeping track of. All in all I am looking forward to trying the full version once I get a license.
