compared with 500 CPL game that I had already purchased these CPL600 were more effective. Indeed, it was to transmit multimedia elements from an office where there are computer and data storage to the lounge equipped with TV and BD player. With cpl500, the flow was insufficient for some films and display the jerky television; with cpl600, no problem. The fact that one is equipped Cpl several ethernet ports is also an advantage (but bandwidth being shared ... it should not be that the application be important on all ports). One of Cpl 2 600 were delivered to me estt showed defective: the day after its first use, it started to heat up substantially (65 ° measured) and the LEDs are off = HS. But with AMAZON, the service is SUPER: as soon as the fault has been reported, AMAZON shipped a new set of CPL BEFORE even receiving the defective devices! EXTRA.
