Ok - have been totally hooked on these with smilomizers for quite some time. I just ordered two and put them immediately on to charge. One is working beautifully, the other does nothing. The button doesn't light. Nothing. I tried hitting the button 5 times quickly several times - nothing. I put it on the charger and the button turns green as usual and it supposedly charges - but when I take it off - nothing. Before I send back for replacement, any tricks or hints I am missing? Thanks!
