Summary: This product is hopeless. After many attempts at trying to make it "learn" I have given up. Considering that everything I have is Sony and it can't ever navigate to the right source without intervention just goes to show how useless it is. After 4 months of trying to use it I have decided to sell it and look for a different brand (but definately not Logitech).
Summary: If you are thinking about buying one... don't do it! Absolutely painful interface, poorly laid out, slow and very inflexible. Logitech think they are being oh so clever in attempting to take out the guesswork... but to say that they have failed would be an understatement! An entirely frustrating waste of time and money. Get something that is fully customisable and doesnt assume that you are a complete moron! I bought one due to the good rating on cnet - big mistake.
Pros: Sleek looking
Cons: Very inflexible! Hard to read buttons. Painful software interface... etc etc. Save yourself - dont buy one.
