I have a vision spinner 2 and everything was fine with it until one day out of the blue. When i press the button you can hear it working but the light is red. if i hold it down for about 5 seconds it starts blinking red. i've tried charging it and it still wont work. when i go to use it there is basically no smoke and it just isnt working. should i buy a new pen or is there a way to fix this?
