Hi, what's out's opinion on tentsile "tree tents"?

I was very skeptical at first, but now I'm rather interested. Seems nice to not have to deal with the ground and to have a nice, comfy are. The price at $600 is not steep compared to other high end tents.

I can see a few obvious problems, like:
>Heavy as fuck at 9KG
>Near impossible to actually hang higher than out heights (false advertising)

My friend will buy this for us to use if I don't stop him...
