Units are about 1 year old but only used for about 7months, worked really well, will easily cover most homes with a strong signal. Selling because I rewired my house and don't need the same wifi coverage anymore. $150 for all 3 nodes, all are the Triband AC versions. The 2 pack is the ver2 hardware the single is ver1, functionally they all worked the same. Come with boxes, AC adapters & 1 network cable in each box. Basically they are these units: https://www.bestbuy.ca/en-ca/product/linksys-linksys-velop-wireless-ac6600-mu-mimo-mesh-whole-home-wi-fi-system-whw0303-ca-3-pack-whw0303-ca/10550800
