WD My Net N750 Wireless Router, Worth Rs. 7200?

Western Digital recently forayed into the wireless router market and has launched WD My Net N750 HD Dual-Band router in India for Rs. 7200. WD promises greater range with their 'FastTrack' technology. The N750 will offer 300+450 Mbps speeds [over Wi-Fi, I guess?]. It offers twin USB ports along with IPv6, DNLA and UPnP.

I wish to know whether WD routers really are worth the money? Is it capable of sending signals say about 50 ft away with about 4 cement walls in between?
