I wanted a mesh wifi system so I bought a 3 pack of slightly used asus google onhubs for $100. They're gigabit routers and supposedly more powerful than the newer google pucks. Onhub is good for 2500sqft/unit where google puck is 1500sqft/unit.$100 sure beats the 259 for the 3 pack of google wifi pucks.
Got them today and had the whole system set up in about 15 minutes. Unbelievably easy. I don't need anything fancier than what I have, I can vpn on my devices if needed. I use to only get wifi in the house and right outside the door. My house sits in the middle of 1/3 of an acre lot. Set up the main wifi hub in the middle of the basement where my utilities are, one upstairs next to the TV and one in the garage. I now can go anywhere in my yard and have full wifi coverage. Freaking awesome. They use the same google wifi app. For anyone thinking about a mesh system, so far, I give google wifi 2 thumbs up.
