If you've been reading this thread for a bit you would see that there really aren't many unhappy EVO owners in North America. I think there was a firmware tweak, and the odd RMA, but i'd be confident enough to buy an EVO right now. The customer service is apparently better than ever, and things seem to be rolling around nicely. Always nice to get an update from SM55, but as expected the CVO will be busier than anything serving the customers.
RE: Burnt taste/smell.... I had this as well with the Cloud+ and it was 100% a dirty bamboo which I was able to clean well enough by letting it run on max temp for a while, then when completely cold i'd use an iso qtip and do the best I could. Also make sure that your temp isn't too high for that particular strain...always best to start lower for flavour. I'm starting to tone things down due to lung irritation/chronic bronchitis, so I rarely go above 2:00 on the dial....would be about 3:00-4:00 on the EVO.
RE: Pop/explosion....I mentioned this when
@lazylathe allowed me to borrow his new EVO. Had it frequently with the EVO, and it was a definite "flash" and poof! pop! But it was harmless and has to do with the size of the bamboo IMO. I never, repeat never have this happen at the same temps with the Cloud+ and my ELBs are a bit looser in the Cloud+ bamboo, which leads me to that theory.
I've been using the Cloud+ alot more lately....damn, I am a VXL and Epic Vape fan, and love both to death, but nothing matches that wide open airflow, volume of vapour, and taste than a Cloud (EVO)!
