Hi all, my first post.
Some history : bought my DV new in Oct. 12. Also own an AR SOLO (wife's favorite), and a AR V-TOWER. Haven't combusted anything this year (my New year"s resolution :>) and have spent the last week reading all 111 posts on this thread. Pretty incredible resource, tons of tips tricks and vapor wisdom.
My Dv is the old model, no serial number that I can see. When I got it I did burn a few dry bowls, didn't know about the off-gassing never noticed any but never thought to look with a flashlight, it had a bit of a glue gun new tv smell but slight and was quickly gone.
Mine never shows the battery meter fully charged (just animating) until I unplug it no matter how long on the charger.
Simple solution for gooey stuff or kiff... load some regular medium grind on the bottom then some of the other sandwiched between another pinch or 2 of regular grind... works for me.
Gotta say I must have got lucky because this thing has served me faithfully since day one and I still see no sign of batteries losing any strength yet or anything.
Vape on :>)
