i have 2 of them. the no logo version from 101 vape. outside of the nice box, these things are garbage. im gutting both of them and putting legit dna chips in them. the red one i have, the Ω readings are always .1 to .2 Ω lower than the legit hana i have. a .5Ω coil is flashing when i try to fire it.
they randomly sleep and wake for no apparent reason. honestly, you would be better of picking up a hammond 1590 box some wire and a dna chip and charger and making one... the box itself is sexy as hell though.
