Unused, only opened the box for testing during purchase, tested for less than 10 minutes. The device is in like-new condition. It can also function as a router. If connected via cable to the original router, it provides high speeds of up to 3000 Mbps. In short, for those suffering from the router's distance from their setup and wanting something to transfer speed as if directly connected to the router, this is it. Search for this repeater, and you'll know it's one of the best on the market.
