I must admit i'm also starting to lean toward the IPV.... what is a 1mm overhang when you have 20 extra wattsI was also very confused, but at the vape meet i got a chance to play around with the hana and ipv, and other stuff. I came home even more confused lol, because both those devices are top notch. But for me the ipv felt more comfortable in my hand, plus its got. 20 extra watts, so i ordered it. It is a trade off a bit in the looks department, as i hear 22mm attys have a slight overhang, and some dont seat flush.
But i dont really care about it, it feels good to me. This is why vape meets are brilliant. Before this, all i knew about mods were from youtube videos and internet pages, but i was so shocked to see how much smaller these things looked in real life, and the weight of those things!
Go to a meet, then you will make up your mind, else, just take either the hana or ipv, you wont go wrong with either
Note, the ipv has its charging port at the bottom, so you may have to remove your atty to charge
