Iam owner of Mecool M8S Pro+ S905X 2/16GB its fine cheap device, all works great. I bought 4K TV and to be prepare for 4K movies i bought suggested usb 1B ethernet adapter, i read its not full 1GB but more then 100mbit built-in my MeCool. Its play fine 4K movies, but i wanna give it my parents so i look another device.
Mecool has two disadvantages:
- 100Mbit ethernet, for 4K need usb adapter 1000Mbit,
- no optical audio out,
So my latest opinion to choose best device for now its between Vero 4K+ or Minix U9.
But as Minix U9 its more expensive and based on problematic S912 chipset (next version of kodi will be not possible) i suggest to buy Vero 4K+ its on S905D its like S905x but with 1000Mbit built-in ethernet port
Read for 4K, HDR and with 1000Mbit ethernet and optical out for audio.
If you add price of additional 1000mbit adapter, usb audiocard with optical out the differences in price between cheap S905X device or Vero 4K+ will be small
If you wanna buy it from second hand remember it must be 4K+ not 4K. “+” mean 1000mbit ethernet.
My suggestion based on needs like 4K, HDR, optical out for audio support
