This is their most-powerful system. Brand-new in box. Don't ask; bought an extra by mistake. Not returnable as I bought it from an American vendor :( That said; fabulous system. Much, much better than anything I have ever tried before in our log house, and works all the way out to our cottage at the rear of our property. Blasts through 10" solid logs. Much better than the Telus and Google Mesh systems I tried, and Airport Extreme, Linksys, etc...
