You'll find that true for everything Iken makes. He takes things and makes them better. That's because he is a vaper and not just someone trying to make money.
This is the automatic battery, I thought this one an item he just bought?
Here is a comparison between the pile of batteries I got had got direct from China and the ones I got from Ikenvape.
The tube looks identical except for the length and the end cap. I can't find any other physical differences. I am pretty sure the tubes came from the same source. The led cap is very different.
The auto switch is a whole different experience. The auto switch on the ones I got from Iken works very well. The auto switch on the ones I got myself require a harder draw to operate, too hard of a draw.
When the batteries from Iken are almost depleted they produce more vapor then the ones I got fresh off the charger. That part does not make sense to me as I figured both were unregulated. Perhaps the switch affects how much vapor comes through.
The ones I imported are trash. The ones I got from Iken work very well.
