All of a sudden my mini will not make contact to make connection for vaper. I had to go to a 'K' model from another manufacturer. I was reading about someone having a sore throat and lung irratation which I am now experiencing with this 'K' model. Where do I get another base,I should not have to shell out another 35bux for the whole nautty unit . All i need to know is if I can buy that part from somewhere,and it is not a copycat.
