I own an Aspire BDC an Aspire Nautilus and a Kanger PT3. These observations apply to all 3. The atomizer heads are constructed with a bottom post pressed into place place with an O-ring creating a contact to complete the circuit when "fired". All three are susceptible to the contact becoming unstable when you instal the head to the bottom "deck". Placing a dab of e-juice on the o-ring to act as a lubricant has completely eliminated this problem. I have also found doing this eliminated leaks that presented as flooding. My assumption is the dry oring was griping and tilting the wire or making a gap between the wire and oring allowing e-juice to flow into the 510 on the Aspire BDC and Kanger pt3, or into air regulator on the Nautilus.
I purchased the PT3 due to the "flooding" and inconstancy I was getting from the Aspire BDC. After having almost the exact same problem, I bought the Nautilus because of the air regulator design preventing e-juice from getting to the 510 battery well. The same problem was occurring but flooding the air regulator instead. My point is the the heads all have the same design issue. Lubricating the oring seems to fix this issue and could very well be the source of the Kanger reliability issue on replacement heads.
