My new one fires on the first FIRM click out of sleep 90%-95% of the time. Press the button and hold that sob down hard for a second and a half and it'll fire right up 9 times out of 10.
So far on my SECOND clone I have the following problems (first one shorted out after my aerotank mega's threading touched the 510 connection for those just tuning in).
Green light will not go on when fully charged.
Will NOT fire on first click every time.
Wattage will go down by itself.
Wakes itself up during sleep.
Crooked 510 connection.
OHMS fluctuate VERY often.
Came with major and minor blemishes on the aluminum.
And I don't even care because when it's working, ohhh is it working
