Started using the Mi Router Pro a week back and have to say I am impressed by the performance vs it's price. I have been avoiding big names such as Asus for quite some time as I feel it's very overpriced, and this 103 bucks router (including shipping) proves the point. At the same price, I am going to be able to get an AC 1200 range router, across all routers from known manufacturers.
The router looks bulky, but knowing that a big heatsink is cooling the chipset, it's quite assuring that it will not overheat even under heavy usage. So far, the chassis just feels slightly warm, as opposed to my experience with Asus N56U, N66U and TP Link Archer C9, which is normally hot.
