At first glance it looks like a router, but this unique signal booster provides the best coverage compared to any device reviewed. It is the most powerful range extender currently in the market.
This device supports the 802.11ac technology and has a USB 3.0 port that you can use to share files and print. It has a 700mW high power design and a dual core band Wi-F up to 1200 Mbps for ultimate range. The dual core processor provides for maximum performance.
Personal opinion : The dual band does it all and goes it well. The lightning speeds are just wonderful: now I can stream my HD videos flawlessly.
