I recently changed to the Smart AV + 200 MBit adapters from devolo. Previously, I had an AV Mini Adapter 200MBit Devolo installed unfortunately had to depend on a power strip.
Ansich I do not need much to write, it's pretty quick to install and ready to use.
Data measurements on average:
4GB large file from the 2nd floor to the ground floor:
Devolo 200MBit AVMini: ~ 20MBit
Devolo 200MBit AVsmart +: ~ 46MBit
4GB large file from the ground floor to the 2nd floor:
Devolo 200MBit AVMini: ~ 7Bit
Devolo 200MBit AVsmart +: ~ 25Mbit
As you can see, the performance has about doubled what comes naturally to the best in an HD video stream o. IPTV.
I say the change is worth :) especially since the meissten the AVMini can not plug directly into an electrical outlet and thus to a loss (in the case of the strip) to resort.
