Overall, I like the Lavatube a lot and it worked great for the first month or so. I then had to start pressing the button a little bit harder to get it to fire, no big deal. Over the last couple days, it's gotten to the point that I have to press and hold REALLY hard to get the thing to fire. It's quite bothersome! I've read a couple other threads about this and have tried the advice they gave (taking the battery out, covering the 3 small buttons with my finger, pressing the fire button and blowing into the open battery compartment, and I also tried swabbing around the outside of the button with rubbing alcohol) but nothing has helped. Any more suggestions other than sending it back for repair? I'm living in Italy right now and I bought it from ecigwizard.com in the UK. It's still under warranty, but I loathe the thought of waiting two weeks or more to mail it and get it back with only my meager 808 batteries to use in the meantime... Thanks in advance for your help with this!
