I bought the Netgear Orbi (RBK50) for our apartment and it is incredible. Far more than I need for the apartment. In fact, we are on the 16th floor and I still get wifi service when outside at an entertainment area that is on the 2nd floor.
So, I bought another Orbi for the office (RBK20W). It is fine for the office, but does not have nearly the range of the other one. Not even close.
