I'm not downplaying the apparent issues with the DNA40 boards that some experienced, but Evolv has been one of the best things that has happened to vaping. Their history has been one of innovation and lifting the bar for other manufacturers. I don't think the one instance where they had an issue (and I have had no problems with four separate DNA40 devices/boards purchased over the past 8 months) is representative of the historical record or "past performance" of the company. Comparatively speaking, the Chinese manufacturers have been much more troubled with quality control than Evolv. The reports are that the DNA200 has not experienced a single screen glitch...I for one am taking the word of the good folks on the beta and will be buying Day 1.
It does seem to have issues with preheat though that hopefully get fixed before release.
