Just a quick update ..... this has shit the bed already, probably due to the amount of e-liquid that seemed to be continually pissing out of it everywhere the last week.
Looked on youtube, not the only one with an issue, tried to fix the issue with superglue and liquid gasket, thought it had worked and carried on using it but there was so much liquid behind the plastic internals (that seem to be glued in) that I couldn't get to and clean, who knows what was still floating around in there, getting all over the board, in the button or whatever? ... or maybe the 'fix' didn't work, I don't really know....
anyway it doesn't work now, broke, kaput, fried .... just thought anyone reading this should know. .. it was about a month old and it's now in the garbage, so buyer beware.
