I am happy with my purchase of the NETGEAR Nighthawk Wifi Extender. It was relatively easy to set up and the app gives me total control. However, I am totally unhappy with seeing PB Tech turn up now on almost every page of almost every website I browse. I don't know or care how they do it but I find it totally saturating and invasive, like a blunt instrument. On the strength of this alone, I would not recommend PB Tech to anyone.
