The R99 has some impressive hardware with 4GB of RAM and the RK3399 CPU.

With those specifications it will have no problems playing 4K Ultra HD videos using Kodi or other sources.

The one downside is the price which is currently high compared to other units.

For those looking for a budget box there are better options such as the H96 Pro Plus or the T95Z Plus.

Overall the price will be the biggest factor since the unit works very well.

While the RK3399 Chip out performs any S905 / S912 box these slower units still work well enough and make good budget boxes.

Many will not have the need for a high end unit with low-to-mid range boxes working good for many users.

As always be sure to read review on Amazon or elsewhere to be sure a unit is a good fit for you.

    Can i play flac files through this? Does Amazon prime video works?

    One thing your review did nit touch on is tge fact you CAN NOT play Hulu or Prime Video. Netflix video player goes in an out (but works). Yes you can install all of the services just not watch them. I have 2 of these boxes and oversll very disappointed in them just for tbose reasons alone. My H96pro and Firestick 1st Gen out perform the R99 4K simply due to being able to utilze all functions and services.

    Mary, what are you using for your channels? Mobdro, CKayTV, etc.

    I have an android a96x r1 bar code number x001jdw9q1 4 k tv box ultra hd 4k 2k and I live in the united states and I am getting channels from UK, Iceland, Ireland, and the commercials are in British pounds, and I want to know how to go from United Kingdom stations to United States channels. I really like this, but I rather have United States and I don’t know how to switch over. I bought this last month and I have not been able to find anybody to help me. I was shocked. This is easier to set up and use than Roku. I just wish I could get U. S. stations. This has been going on for a month now I bought it new. The language is in English, but British English and I want to know why and how do I change it? The movie stations are american, but the local stations are from countries like Iceland, Great Britain, and Ireland, and the United Kingdom. I don’t understand why I am hooked up hdmi, and it works great! There is no instruction manual to tell me anything.
