I'll start, maybe some vets will chime in too.
1) Use is normal, but ensure you don't let em get "dry" while
vaping. They get too hot, the wire can burn/break.
2) Don't use em on hi volt mods or on 5 volt pass-throughs. Too many watts... burn/break again.
3) Cleans normally. Cleaning is a whole can of worms in and of itself. Many threads and opinions. You may wish to try distilled water rinse, blow out, let dry or vape 'till almost dry (don't inhale the steam just "puff it"), add
juice vape till it works.
P.S. Try not to clean em unless you have to.
P.P.S. Someone had to answer; we almost had another "snails" thread situation....we would have had to start a "turtles thread"... it would have been ugly. (just a little ECF joke StuckinLA... Watch for snail signatures...) FYI - If you had posted this question in the new users forum or the general area you would have had an answer in 5 minutes (man... those guys/gals are soooo fast!)
P.P.P.S. Congrats on 3 weeks.
