That's a good pickup. I've been eyeing that Vaporshark for a long time. Thought if I did, I'd get the rDNA40. I really like the small profile.
I was really looking hard at the rDNA 40 also... it's only slightly larger and has the option to change out the 18650 that it uses... I really liked that it uses a changeable battery... but on the other side I don't usually use more than about 1000mah if I'm just out and about and I can charge from my truck if I do need more.... I currently don't vape at more than 14w using single coils, with dual coils I should still have enough with a 30w and finally of course the added $70 more in cost factored into it alot also.
Another advantage on the rDNA... they are currently reworking the case to use magnets instead of the hex screws on the cover, which I'd like also.
