I let the first adapter installed by a qualified electrician, when switching on the fuses hats smoked out of the machine and the FI has fallen. Our first suspicion was natural that the electrician has made a mistake, but we have everything checked again. So DOA (Dead on arrival), since I bought the adapter on the market place, it took about 3 weeks, but I got the money back and just bought a new directly through Amazon.
Leave installing ..> works great !!
I use it along with the Netgear Powerline 500AV adapters (because I already had this).
Also works great! Ping has fallen from 75 to 28 !!!
