Yes I have a pair of those (85Mbps). They work fine HOWEVER the 85Mbps 
is some marketeer's dream. I googled them before I bought and apparently 
you should expect ~8Mbps. In my experience, even that is a push. I never 
made any measurements but I could not reliably stream a Freeview bit 
stream in native MPEG 2. I had to transcode it down to MPEG4 before it 
would fit through the available bandwidth. So I guess that means it 
wasn't working well enough at 6Mbps but OK at about 3-4Mbps.

My installation was on the same phase but different circuits. It makes a 
difference, from memory I got 6Mbps+ on the same circuit (which was no 
use to the intended application). Using an extension lead, 4 way socket 
extender or double adaptor all cut down on the throughput. YMMV.
