Hi everyone, 2 days ago I bought 2 fantasia E-hooka's, I opened up both, and used them since then. One I have barely used, and it is producing no vapor. The other is alright, but has kind of a weird taste to it, compared to that actual shisha (same flavor). I looked at the boxes and both say that they were best before Dec. 2014. Im not sure if that is the reason for my problems? Any ideas?
