So, I'm planning on upgrading from my Vamo V5 towards the end of the month, and as much as I dislike the overall shape of the box mods, there aren't any small form tube VV or VW mods that really do anything for me. So after browsing the forums for a bit I'm leaning towards the Hana Mod with the 30W chip, or the IVP V2 with the 50W chip. I am already building my own coils on a kayfun lite clone and Protank III's and just about have the kinks ironed out in the simple coils and will probably pick up another kayfun and maybe a RDA of some kind. Right now I'm leaning towards IVP v2 in part due to pricing, and the ones I've seen appear to be authentic (leaning towards this one 50 Watt Box Mod IVP 2). The only reason I lean towards authentic is the safety factor followed by the reliability factor. I've read to many varied reviews on the Hana Mod clones to feel really secure in ordering one, and I'm also bit anxious regarding ordering batteries to go with either one. The one thing that does draw me towards the Hana Mod/clones is the size, especially the mini version. Could someone point me in the right direction regarding reliable and trustworthy sources for both? Im hoping that this will be my final VV/VW mod until I make the switch mechanical mods (mostly for form factor/appearance) so I want this to last.
