Use mine regularly, second time I attempted to charge it nothing happened. No lites no indication that it was charging. I contact MyFeal and received return details straight away. I went to pack it up and checked that I had all the cords and plugged it into the power pack and the indicator lightscame on and everything worked and 3 months later all is still well with it.
