My wife and I bought a bunch of these myblus for a disadvantaged elderly woman she knows, and they actually worked! I ended up switching her to the Boulder pen that BillW50 posted about earlier because she couldn't pull off refilling the myblu on her own. She is trucking along with that with the juice that I make for her, and she's now been smoke free for 3 weeks.
The transformation to her health has been quick and dramatic, and she received good news from her pulmonologist for the first time in her life yesterday. She was in really bad shape before the switch, and after seeing this transformation first hand I am truly astonished (even as an experienced vaper) of the health effects of switching to vaping from smoking. Unfortunately I'm also even angrier at the lies from the Public Health orgs. Regardless, thanks to all posters on this thread. Amazing!
