I found with weeks of time hands on with the software that it added a lot of features that I wouldn't want to live without. Unlike some other multi-monitor software that I have used before that was invasive in some way often crashing on me or behaving strangly. I have not noticed any bad things or bugs in this software.
In addition to the standard affair productivty features like multi monitor task bars, I was really impressed with the uniqe features like mousing out of full screen games (Ignore Deactivation) and the move windows from any position feature.
It's the small things like this that I think make this software stand out the most and make it worth consiterting for purchase should you use a multi-monitor setup.
