Query: Difficult to configure and does NOT work with many devices.

I bought it thinking it would be really easy to configure and that almost any device with remote control will work with it. From 10 devices that I have only one was on their data base. And the manual configuration is very difficult. I would rather bought a much cheaper universal remote control instead of this one that says it is sooo wonderful.If you are thinking to buy it, I recommend to try it before with a friend or store and check if your devices really work with it. It is too expensive for what suppose it does.
