MicroBoard V490UHD HDX

I've been watching for Microboards on fleabay and not seeing much. Saw this one show up today.
Been focusing on the wasabi mango 49" but I do like the looks of the microboard.

Has anyone played with this? My googling hasn't found much for reviews.

I couldn't tell you super specific technical details but I've had the 43" version Microboard for several months now and I love it. Super sleek and very well built. I game on it, and use it for daily browsing and movies and such. Fantastic display.

I am sorely tempted. It would make a fine monitor.
