I had the previous one MI Box 3, and bought this successor product hoping for some improvements. The quality of the MI Box is inferior in every way. The remote got cheapened. The prior one was contoured to fit in the hand. This one is squarish clunky with a poorly designed 4-way button. The "back" and home "buttons" are in the wrong place, contrary to the previous one, or Android phones. Who uses the middle as the "back button"?. Design of the home screen is done to promote what the google AI (Artificial Idiot) wants you to see instead of providing useful layout for selecting what you want to see. Worst of all this thing cannot do pass-through digital audio. So any surround sound is degraded to two channel. This includes all of Netflix which mostly Dolby Digital Plus. Forget about any DTS, DTS-HDMA, or Dolby TrueHD. This thing will render your home theater receiver useless.
