When I read the other Rezesionen I immediately checked whether the device is actually so hot. I can absolutely deny. I had the unit 2 days in continuous use and it was only lukewarm. Picture and sound are fine, the operation is simple (except for the channel list management - therefore 1 point deduction). The integrated electronic. Programme Guide is very fast and really very good. Previously, I had the D-Box 2 Nokia. This all happened much slower (eg construction of programs ...). Even switching between TV and radio is much easier with this device.
