well im pretty happy with mine. Used in in a 3 story house, one in each floor. Maybe once a month need to restart the unit as it has weak connection for some reason. The instantaneous switching from one mesh to another when u move to another floor is really impressive. For some reason, only my phone will show "no internet" after switching from one mesh to another. If this happens, just reconnect , which is annoying to deal with. But overall its a good investment if u have a big house

I tried replacing the unifi router but didnt really work for me, so i just plug it to the unifi router as a 2nd router and it works without much setting up. Maybe u can solve the issue but i dont really want to hassle so just plug it in unifi router
