I went to the House of Hybrids Lounge in Rochester NY and Mike personal handed my ZNA to me...all you have to do is call ahead and he will hang out if he has the time. They have some cool stuff to check out and I love my ZNA. I use a modified Sidewinder RBA, Z2 Mini Atty, and the 510 works with everything under the sun...the only thing I would recommend on the 510 adapter is to get a couple of extra screws for it so you can grind them down to specific atomizers to get a flush look...my kayfun lite doesn't sit flush.....but it doesn't take away from the performance or craftsmanship.
