I like to personalize my desktop. It took me a long time to find something 'extra' for my mouse. This is one of two apps that allow me to do this. I had a hard time setting magic mouse up. But, I am glad I kept at it. Magic Mouse has some of the coolest effects, and the community has added to that. The only problem i've found is that the mouse itself doesn't show up when navigating any windows menus (like the start up menu). This could be because I am using a 3rd party start menu? It does light up the programs as if the mouse was there so its not bad. I kinda like the 'dramatic' start up effect it has when you open the program. I really like this program. I would recommend it to anyone that would listen. lol
