That booster gotta be defective.
There should be a significant difference between low an max voltage.
At top high everything I have tried taste really burnt and makes me cough my lungs out of the body.
Anyway it should not be crooked.
The fact that it is crooked really bugs the crap out of me because I have OCD when it comes to perfection.. but I could learn to live with it if the booster actually boosted anything..
I notice an extreme reduction in vapor when I turn the knob to counterclockwise to 3.3 volts but when I turn it all the way clockwise I see no difference at all. I have taken off the booster and put it back on a number of times and it is the same as having no booster attached.
I have tried different batteries to try and correct both problems and they both persist...
When I opened the mailbox I was really happy but now I am really sad and frustrated.
