Well, you need to have alternatives ready for when the daily driver stops. I got 3 Iolites to maintain 1 working one (now have 2 workers!), got 2 Solos (seller sent 2 billed for 1 my win!) LB (never did like it at all) and a couple others of no use or mention. So now since I ordered one of these from Ploom's site, if it has problems I have something to fall back on. Even a cheap box vape with an Arizer 'stack' or chimney or whatever on it with elbow and tube can work really well for under 100 bux. But, since seemingly anything _can_ fail at times, if it is essential for you, you must have a spare.
I got black like all my other electronic stuff is. I am concerned about the bottom falling out/getting lost, or the top springing off and getting lost. Stuff can happen. Apparently the thing isn't even waranteed against acts of piracy. I have never seen a company exclude that before so I am concrerned. However, the general feeling I get is that most are impressed with the unit. Unfortunately sometimes getting a manufacturer to actually do something takes time and many of us are impatient. (Took literally months and months to get one Iolite repaired/replaced - way too difficult so I gave up on the 2nd broken one.) So, the bottom line is that it is unfortunate you aren't having the joyful experience many seem to have, but (a) don't give up and (b) strongly consider having a backup plan B vaporizer ready in the wings to spring to action if/when your main unit fails.
Hope it all works out or has worked out for you.
