Thanks, just received my 20$ mod box, 3.7 volts, 808 connector, using a 14500 battery, design is nice, sturdy box, on/off switch, a little bit bigger than a bic lighter, it's really small and convenient. So it do looks good, but I can't get a consistant vape !
I press the button, the light turns on but nothing's happening to the cartomizer (no sound, no sizzle, no vape), I need to press very VERY hard to make it work and sometimes it doesn't light the cartomizer. And when it do work, the vape is kind of cold, looks like it only draw 1 volt. I tried fresh charged trustfire 14500 from dealextreme and IMR 14500 from clouds of vapor (this one needs a spacer to be able to fit), and I used these batteries on all of my 3 wetbox until they died (this thing is crap, the switch always die), so I know the battery do work. Absolutely no juice leaked inside.
I need to point out that it did work fine for about 10 minutes when I first tested it and I was pretty much happy. Seems like everyone else in this thread has been able to make it work, just not me, what a shame.
