Well I have 8 Porter Port Duplex and 2 Isoclean single outlet. I certainly prefer Porter Port, at least for its connectivity. It grips the PC plug real tight unlike Isoclean outlet. When I connect a heavy PC to Isoclean it has a tendency to get pull out slightly- poor grip. However construction of Isoclean is 1st clean. It shld be with more than double porter port cost. anyway i m thoroughly satisfy with porter port
