1. The machine claimed to be native full HD, however it is not, it comes with 0.33 DMD chip, will pixel shift to full HD. It is not native full HD!!!
2. 4K video playable, but not watchable. Enjoy your mono-color Avata. ex. only red or green color on the video frames.
3. I found sometimes the screen is flickering as you can see from the video...
4. this machine does not implement voice control correctly, Alexa does not work, after voiced instruction, Alexa just freeze without any respond.
5. Looks like there quite a bit of apps in the store, but because this machine is not Google service Licensed, quite a lot of Apps cannot be used.
6. This machine is powered by LED, but supprisingly, it has serious rainbow effect as the 3-lasers(Trichroma) projector, the image appears to be blurry in general. If you watch for half an hour or more, you will feel dizy and eye fatigue. What's the point of the LED? It should be the most gentle light source.
7. The video color appears to be very very very over-saturated.
Therefore, no doublt, this is a bad purchase.
