Agree, I hope he'll enjoy it too. It just seemed like too much work and when it worked it was too airy, so as long as the Penny works out I'll be happy. I'm keeping in touch with the buyer so I can learn from his experience.
Well now that I have quite a few tanks through the ZAP and DUD I can say I prefer the flavors I get out of the DUD. Crazy I know but the $20 DUD in my opinion has better flavor than the $150 ZAP. The DUD also seems to produce thicker vapor.
I'm not ready to jump ship on the ZAP yet though, maybe rewicking and recoiling it will improve performance for me.
