I have had good experience with this smart router.1) USB Hard disk option: The first thing that I liked about it the ability to plugin a USB harddrive and being able to access that harddrive from all mobiles/tablets and computer.It's like our own private cloud. When my phone 's memory is getting full, just with a few taps I can transfer the photos/videos from phone to USB harddrive connected to my router.2) Range: Second thing its range is definitely larger than regular 3-4 thousand rupees routers. it can easily give signals upto 30 feet even if there were two concrete wall. I also tested that 4 concrete wall and after 4 concrete walls signal would become poor, I think that's fair too.3) Speed: Speed is amazing, my work requires me a to have a lot of video conferencing meeting. All my meetings goes pretty smooth with HD video conferencing.4) Looks: The vertical router looks classy
