So I bought another box as mentioned last week. It's the Mecool M8S Pro L 3gb/32gb S912 with Android OS that came with the optional voice remote. To those intending the same, get the voice remote, it's worth it!
I must say is a very fast box with a refreshing UI (unlike most boxes that comes with a boring static UI) Installing apps was a breeze and a lot faster compared to the last S912 box or other S905X boxes which I've bought and sold off.
There's plenty of video review available. Some apps I'd need to sideload but didn't encounter any problem
The usual Kodi, Terrarium, FreeFlix all installed smoothly. YouTube and Netflix plays in 4K.
As I just got the box this evening, will try to install other apps and try out.
So far I'm very impressed it and looks like it's gonna be the primary box replacing the Q16 Quad I've had for years.
Wife and kids love it so much especially the solid build voice remote. This box does not have passthru capabilities but it's expected when I decided to buy this.
