Long story short - may get longer later:
My wife bought a vaping kit from a shop in Chester on the 2nd July this year. £50.
Product is here: http://www.innokin.com/vaporizers/cool-fire-iv/
When I first got it, it seemed perfect, worked well, did what it was supposed to do.
At the end of August it basically stopped working. Put it on bedside table before going to bed (pressed button 3 times to put on standby), woke up the next day and found it completely dead, nothing seemed to spur it back to life (charging, pressing buttons, checking physical on/off switch on bottom).
