Bests & Worsts Reviews from Amazon

long story short, the EERO router works as advertised. I currently have 400Mbps down which is roughly what I get near the router in the living room. Unfortunately, the extenders are useless. In fact I receive higher speeds from the living room EERO router (150 - 250Mpbs) than I receive from the extenders (65 - 90Mbps) directly next to my device. Now I have all my devices connected to the router and in a dilemma what to do with these useless extenders. Note: I have already applied the firmware update for the extenders. They did not change anything Believe me when I say all i want is the device to work seamlessly and to receive atleast 90% of 400Mbps across my 1200sq ft apartment. Now what to do with these extenders
