Providing overdue feedback on seller after sorting things out on my end. Managed to COD rt-ac66u with seller at Mid Valley early April. Overall seller is responsive and transaction is smooth.

Item received is also working in order and as it should - good penetration and wide coverage, better than my current n56u. Normally the wifi signal is almost non-existent at the kitchen and third bedroom (with router placed at front of house due to usb modem reception) and my cctv cannot pick up the signal as well. However, I managed to get the whole house covered with rt-ac66u.
