This Eero WiFi system covers a 2-4 bedroom home. We had a large 4200 sq.ft. home with thick adobe walls and this 3-piece set gave us great wifi connectivity throughout. If your home suffers from dead spots, slow spots or buffering problems, Eero's TrueMesh router and two beacons should do the trick for you. Although this set has been used, it looks great and comes in the original box.
