Leider ist die Verbindung zur Tastatur und Maus nicht so stabil wie gewünscht. Richtig ärgerlich wird es, wenn die Zeicheneingabe auf Dauereingabe "eingerastet" ist. Hier hilft dann z. B. nur Quellenwechsel. Die Fernbedienung schaltet trotz Nahdistanz die Quellen nicht immer um. Wenn man mit dem Makel leben kann, dann ist es aufgrund des günstigen Preis dennoch zu empfehlen. ## Features - This KVM switch is for four computers to share one set keyboard and mouse and 1 monitor.
