As reported in many forums, the evaporator is supplied unfortunately only half fit, which is primarily due to the evaporator heads. After a few days, sometimes occur from glass fibers even after hours and the first dense vapor and quiet operation there is over. The first (already mounted) dual-coil evaporator head was still the best and has held for 5 days the 2nd was a complete failure (after 5h extreme fiber exit, sizzle, Siffen from the start) and the 3rd has been closely sizzled and now after 3 days depend also long fibers from all 4 holes. Not only that the wear of the heads is too high, these things come partly broken out of its packaging. Other customers report on the forums about a defect rate of 2 pieces per 5-pack. What is Kanger affords as totally unacceptable.
From the theoretical 2,8ml tank capacity are due to the lack of evaporator technology only part available: Once the liquid level has fallen to 20% of the viewing window, it is with good vapor also over. Since volt wheel and air control help anything without reasonable evaporator is useless toy. After all, I did not have to find other people like that Liquid exits the evaporator in the battery and re-emerges through the sunken and relatively heavy tactile actuator button.
If you have to replace the evaporator anyway, you can also equal to an adjustable battery of another company or the EVOD VV 1600mAh buy individually from the set and combine it with a good vaporizer. The set is good so at least not much.
Edit: Meanwhile (8 weeks after purchase) also has the charging cable up the ghost, the LED is off and the battery is not loaded properly. Too bad that when Kanger the quality is so rushed to the basement. Who buys something as primary FR is probably not long when steaming, but certainly not last long at Kangertech.
