I am very pleased with this app. It integrates very nicely with my system (just a clean little menu bar), and I like the fact that you can change the information displayed in the menu bar to the utmost degree (you can display just icons for a "clean" look, or text for more info). I got it when my mac was having fan issues, and it actually helped me diagnose the problem that the apple technicians could not solve (actually, it was an Apple certified repair facility, not the Apple Store - my first mistake). Anyway, the fan was running, but the temperature was not increasing. This app helped me figure that out. It turns out that when they did the work, they did not re-attach the wire to the fan. Simple fix! Now, I use this program to quickly monitor my computers' stats.
