Ah cool! So you have practical experience - how’s that all going then? The biggest Dasung I saw on my quick search was ~13”, and very expensive; do you feel like yours was a worthwhile experience?
For me it's kind of pointless indoors and the weather is not yet ideal for outdoors. When I did use it outdoors (a couple of days) it worked as advertised, but using an external monitor was awkward. A notebook with the same panel would have been much better.
TL;DR: probably not, but I'm still evaluating. (A proper stand for it might also help - what's included is laughably flimsy)
