Decent

The app connects to my iPhone 5 with no issues (the instructions are a bit confusing though). Sound quality is decent.

Pros:
-No longer disconnect from your computer screen in order to take calls.
-On screen and audio notifications of incoming calls
-Gives on-screen options of where to answer

Cons:
-Needs keypad while in calls (Currently cannot enter extension numbers, etc once a call is placed
-If you try to decline a call for with call waiting, it hangs up both calls.
-Menu Bar icon flashes when you click it (as if it is trying to open the app screen) but does nothing - thus requiring an app icon in the dock to make it accessible.

Overall, not a bad option. Hopefully they will continue to work out bugs and issues to make this app really a usable business tool rather than just a neat add-on.
