Ok......I normally love Bud tanks.....but the last few I got are freaking me out.....only used them a few days, a week at most....and suddenly they're not putting out much vapor, or either they have an awful burnt taste. The atomizer is still working.....you can hear it. Are they a bust? Any idea what could be up with these? I would say a bad batch, but i got several from different vendors. HELP!
