Negatives: The channel lists / favorites list is rather cumbersome to manage because of OptimusS has no display, I can do it also for radio reception not recommend. In particular, the remote control is getting used to if you completely pushes a particular key you send the command several times in succession - ie program 111 instead. 1
Positively surprised me the external IR receiver in the package.
Conclusion: Good for the money, those who use a universal remote control and no need display is difficult to find something better - especially if the receiver should be hidden!
