Awesome router! Previously had a $30ish TP-Link 802.11g "300 Mbps" router in my office that was only giving me a max of 30 Mbps, but more like 5-6 Mbps more often than not.
Switching to the Xiaomi AC router immediately bumped that up to 55 Mbps down / 95 Mbps up, and cut the ping in half to 3ms (from 7-10 ms).
No gigabit ethernet but you won't find anything in this price range with the feature. Definitely an awesome AC router for the price, and looks sexy too!
Camera is fantastic given its price compared to its nearest rival the GoPro 4 costing three to four hundred bucks. Only down side is that it has no screen or indicators as to what mode is on, unless you link it with a phone.
