Anyone have a portable screen?

I think there's two in the market, HORI and GSTORY.

I cant find the HORI one here, and I think it works on 120v only.

GSTORY is being sold by some retailers, however I'm not sure if it's good for fighting games or FPS (1ms response rate).

It would be good if they did, since these retailers are selling it at RM800+.
You could already get a decent 1ms monitor at that price.
