I have the PV 18 to 14 adapter and it's pretty damn good, it's different from the WPA but I really like it. Then again I also have the WPA, I like variety.
No issue to report here, I leave it on for an average of 8 hours a day. Best to check for yourself, each unit is unique and local power, atmospheric conditions and the temperature you vape at will come into play.
Although I never leave my LSV or my SSV powered up when unattended for any...
I have both styles, the GG is less fuss but will have hotspots, the classic style is better for more even vaping. Just grab the hands free silver thing if you sick of holding it.
Interesting piece though I'm I'm sure I would wind up snapping the Pipe stem at some point, still that and the double disk ash catcher are very tempting.
I'm not a pro dabber but I would still think less air dilution would be better? Also less glass for the oil to condense on. Hopefully some dabbers can come along and give you some better advice.
Nope just the three I posted, if you have a link I'll check it out.
Also If anyone finds any great prices that are limited to a minimum order of 10 pieces, maybe a few of us could go in on it? (I would, anyhow) All the truly great stuff I see is limited to more than one piece.
