The X9 is a tiny little machine with a decent output [depending on the source of course] but carries with it some limitations but for the price doesn't disappoint too much.
Cons:
The X9 cannot be operated via the machine itself, there is only a credit card remote control. If you loose it or it breaks, you can't operate the machine at all!
One HDMI input and no external audio output - you have to take sound from whatever is plugged into it, it doesn't output audio through the HD cable.
Not great in sunny daylight conditions
Pros:
Tiny, lightweight and very quiet fan noise
Easy
