Thought I'd try out the njoy king since it was free(just paid shipping). I started using it this morning and it seemed decent, though a little bit of a week hit compared to what I'm used to. I took a few hits off of it and I was starting to like it a bit as I got used to it, then the battery died, only took about 20 puffs of of it. That was'nt even worth the "just shipping" I paid for it. I Don't think I'll be buying another one. I don't really use disposables, but if I would find something that worked I'm sure there would be situations where I would find a them usefull. Is it pretty common to get dud disposables, njoy kings or otherwise?
