Welcome

The iJust batteries are flaky. Even the newer ones. I have 2 and both are not working 100%. (Switch issues).
Twisp are well-known in South Africa, as I remember - an 'off-the-radar' brand out to make money. They have little business elsewhere to my knowledge.
At least the rip-off US brands actually use products made by the most successful Chinese manufacturers.
You have to be careful with brand shops. They order from Kanger, Eleaf, Innokin and Joyetech etc. and get them to make small cosmetic changes and lazer their own logos on the hardware to charge double, sometimes triple.
Then they pay fake review sites to recommend them.
This is how the #1 US brand (well, they call themselves that
) charged $119 for a $29 e-cig.
and $59 for a $13 tank.
I use box mods nearly all the time and the Eleaf 0.3/0.5ohm coils are actually my preferred factory coil. At home, I use RDAs.
