Kodi does not come installed which is easy to do from the Play Store.

I installed Kodi 17.6 Krypton which used very little resources in System Info.
 
I also installed some of the current top Addons such as Neptune Rising which it had no problems with.

Testing the unit with Netflix it would only play standard definition due to Netflix restrictions.

Netflix requires a box be certified or it will only play 480p and not HD resolution.
 
While the X99 has the hardware to play HD 4K video Netflix streams will play at only standard definition.
 
Testing the WiFi I used SpeedTest.net Ookla App which gave some impressive results at 163Mbps Download, and 21Mbps Upload.

Running AnTuTu Benchmark Version 6.2.6 gave an overall score of 76606.
 
UPDATE: Others having been getting different AnTuTu scores ranging from 60000-70000. This is likely due to AnTuTu recent updates. Version 6.2.6 was used for testing with no Apps running in the background.

Other scores are 3D: 1507, UX: 33855, CPU: 23427, RAM: 3817.
 
I used 4K YouTube videos to test the video resolution and it had no problems playing any 4K UHD videos even at 60fps.

Summary
The X99 comes with some nice hardware for streaming videos and did not disappoint.
 
The AnTUTU score of 76606 is very good even higher than the Fire TV without the restrictions.
 
It will have no problem running Kodi, Netflix or most any other video streaming App.
 
I am still testing the unit so far with good results and will update if anything changes.
 
As always be sure to read the reviews on Amazon, forums, or elsewhere to be sure a unit is a good fit for you.

    People its not the rock chip its the build with a bad fork installed. You can try to reset box as soon as you get it cause I think some Chinese guy put a fork on box after mfg. Or install Chef Kodi 64 bit or install a different fork yourself. I would reset via botton in back. Worked on my X99 box which flies! Really fast box with no problems. S912 cpu is nicer but only 32 bit builds are out.

    I have given up on these Android boxes and Gearbest as well. I will only buy locally where I can return the item without hassle. From my experience, there’s too many counterfeit and cheap chipsets that render the box useless. Most recently, I had a bad with the H96 Pro+ by Alfawise. Reviews seemed good until I googled the issues I was having. Then all sorts of issues popped up. Instructions to reinstall the factory firmware are lacking too and you need to take the box apart to see what chipset there is.

    I’m done with these Android boxes. I will only buy a premium Android Box like Evpad or use my laptop connected to my TV.

    I am having a problem with kodi. It will load a build and appear to run fine, but after a day or so, kodi loses the build info and reverts to a first run state. Also happens on a power cycle.

    I also have an H96 Max with the same build, 7.1.2. It does the same thing with kodi, so I am thinking this is maybe an rk3399 platform problem.

    Another disappointment is middling antutu scores in the low 60000 range. I am going to experiment with some cooking techniques to see if it is a thermal related issue.

    Another problem is losing setups on alternative launchers like nova. It will appear to set up fine, but after a few starts will lose the widgets and I have to start over. I do not recommend this box. The H96 Max is much faster with fewer bugs.

      Hi

      Its totally true and agreed with you
      Dont buy this unit ever!
      For KODI(even 17.6 or 18.0)useless! such as if you power-off unit than you will loose all your installed
      Kodi addons! so you wont do it power-off with this device;like a “joke”!

      First I’v tried to load BUILD but when I’v power-off than all addons gone for ever!
      Second time I’v installed couple of Addons(such NeptuneRising and MagicDragon)then when
      I did power-off device than lost/deleted all my addons again!

      So this device never work stable with any Kodi version too
      Kodi still remain but your all addons lost so never power-off this device!

      Seems that RK3399 does not stable work with Kodi!

      Device also very hot!

      There is a lot of BUGs!

      Need a big updating/upgrade

        Hi,
        I have a X99 with the same problem as you.
        Kodi 17.6 does not work.
        Avery time I disconnect the box from the power supply, I loose everything that I have installed on Kodi.
        This box has a serious problem and I hope there is a upgrade to fix this problem.

          Hi,
          You’re right when using kodi 17.6 powering off you will lose all add ons. I installed XBMC 18, which is essentially kodi 18, and I can power off the box no problem all my add ons and data remain now my box works great.

              Bit surprised to read all the negative comments about my box and setup. I have H96 Pro+ with Kodi 17.6. Never a problem. Switched off every night, on again every evening, no loss of addons or selected favourites. I did install a ‘magic’ rebuild which I hated, so uninstalled Kodi, reinstalled 17.6 and had to redo all my addons and favourites. Absolutely no problems. I’d recommend to anybody.
