hello first poster here, so i bought the mflb and don't care for it. I need to buy a real vaporizer and was thinking of the dbv or lsv, but have a few questions. 1)how much is stealth with the these two? could i open a window and blow out the vapes and someone in the next room not know i am vaping? what if i just fill the bowl half way, wouldn't that reduce the smell? 2) i was wondering all the authorized online dealers of these two vapes. Vapeworld only has dbv, but is out of stock and vapenation doesn't accept paypal, and does anyone know if 7th floor accepts paypal?
