I have 4 pieces installed in the house and I'm thrilled. I have had several older models from other companies, but did not go so well and took us more power, most have become really hot. Everything is just right. I have 4 pieces simply plugged into the outlets and then one to the router and the other 3 in each room to the PC and lo and behold, no one emulate all immediately went and now I have fast internet also in the room on TV and in nursery my son.
