Good morning.
I think there is a lot of hype going on about this atty. I have seen a german review (my native language) where the reviewer had some issues with dry hits if he vapes mouth to lung style with the biggest air hole opened. This was because there was not enough negative pressure to wick the coil. He owns also a Origen Genesis V2, a IN'AX and many other Genesis attys and stated that the NextGen will not his favorite atty.
Not to say this atty is bad or something. But I think there is a little bit to much hype around it. Normaly I only buy authentic attys, but all the ....ing facebook .... annoys me. I ordered a clone last week to see if the hunt for an authentic is worth it or not.
