@inicapem:
If you're getting a foul taste, it may be that your atty needs to be fully cleaned, not just blown out. If you search for cleaning methods here on the boards, you'll come up with about a billion different methods from rinsing in cold water to boiling to soaking in cola to denture cleaning tablets. I was quite cavalier about my cleaning method and used the "crest pro health" mouthwash, followed by a "rinse" in 95% grain alcohol. I hadn't lost an atty until I had my first 602 atty die on me yesterday. Was vaping along just fine on some tobacco extraction that I had made and mixed up with VG when all of a sudden the vapor stopped. I swapped batteries and that (obviously) didn't fix the issue. I took out the multimeter and tried to measure resistance, got no reading. I guess the coil itself just died altogether. I have no idea if my homemade liquid played a part in this, but I have been using my 602 as my primary PV since my order placed on 12/2 arrived. My PV has been dropped more than a few times from mouth height unto the concrete floor in my condo, so I have no real complaints about overall lifetime of these parts. It was just weird that it died so suddenly.
