I finally got one and so far so good.
and these are my impressions so far
1)it doesn't leak if you wick it right, 3.5 seems to work best, wide as possible
2)good capacity 5 / 6mls
3)great flavor.. if you build big and wide this thing is fantastic. better than the sherman and other 30mm rtas
4)huge build deck
cons:
1)expensive
2)i didn't like the oring in the airflow ring, if you damage it it would be a pita to replace this
3)can't use your drip tips

although the one that comes with it is very comfortable
overall it's a very good rta if you don't mind spending 100$ and you are in to 30mm tanks
