My xhaler has recently begun acting up. The switch won't fire most of the time, and I can't figure out what is wrong with it. I cleaned out the switch and made sure it is making contact with the body, but still, it only works about 10% of the time. I use this at 6v and 3.7v with 18650s, using 510 attys and cartomizers, and all combinations still act up. Could it be a short somewhere in the body? Any feedback is appreaciated, as the xhaler is my favorite pv. Edit- I just ran the xhaler at 6v, and while it worked, it didn't feel like it was *really* 6v, and the body got hot, espeacially where the button is located, so I think that it's definitely a short. Any ideas how to fix it? Edit 2- Got it fixed. I took apart the switch itself, and found a ton of black gunk inside it. Cleaned out the inside of it(the switch) and its working like new now.
