The performance I am very confident. Transmits the full speed of VDSL 25th If the data in the laptop and Smart TV stably transmitted. No crashes over 1 hour each. NEGATIVE: The devices should only be connected to wall outlets and not of 3 or multiple sockets. In my test, it really did not work at multiple sockets with switch and filter. Simple 3 plug (without switch and filter / surge protector) were with me OK. So who has trouble using a free wall socket, should the parts for sale with its own outlet to policy. CONCLUSION: Buy recommendation.
