I bought the Harmony 700 after reading most if not all of the reviews on Amazon,and I did have a concern that setup might be a bit tricky as some of the reviews had indicated, and perhaps this made me more inclined to take my time, and to read all the information available during setup which though it may take a bit more time, it made the whole process very easy, and I had all my devices working just the way I wanted on my first attempt.
Ease of use,during setup, you group certain devices together to create an activity-watch TV-listen to music-watch film etc so that with a single button press, you can have the required devices working together. There is also a sub menu called devices which gives access to the features of the individual devices that are stored should this be required, in short, using the "Harmony 700" is just as easy as using any ordinary TV remote. After the initial charge, my unit lasted about 5 weeks before needing a re-charge (this took about 3 to 4 hours)
Overall, I am very happy with the 700 and would gladly recomend it to anyone.
