The newer CE3 types are manufactured by
BetterLifeTech and I have been using them for over 4 months.
They ship with primer (shipping/antibacterial fluids), some of them have a little and others will have a lot, even in the same box. It's not a big deal, as I clean prior to use.
Also do not remove the top seal by prying it out using the filler hole. If this hole becomes damaged or enlarged, they will leak.
I have used 510 drip tips with mine and have not had any issues, however, the aluminum tips are rather large and will stretch the plastic tub which in turn make you smaller drip tips want to fall out.
I posted some info on these in this thread if anyone is having issues.....
here.
Edit: added BetterLifeTech link. Also, they were talking about changing the name to CV3 since Microcig coined the CE3 name from their smokymizer brand. There use to be a disclaimer about this on their site, but I don't see it anymore.
