Hi,

I have 4 in the house and all work great, 2 in living room and 1 in bedroom all feeding off the main one in PC room and stream movies, music, radio etc with no issues. Noise, I've no idea as I've not used anything else so have nothing to compare it to and I'm happy with them, far easier than Wi-Fi dongles or long runs of cable that's for sure.

The TP-Link AV500 ones I use have been rock solid with no issues, whereas the much more expensive DeVolo ones I had were returned as they were hopeless.

TP-LINK Av500 that I use HERE these are twin port ones but singles and trebles are available too.

Mike.
