I used to have a joyetech eroll, and I'm interested in what has changed in the years since that came out. I see migcigs has a chip in one of theirs that keeps a constant voltage so no diminishing vape as the battery depletes. I see the Vuse has an app where you can monitor the charge and puffs left on their ecig (useless imo but app controls for cigalikes is a very good idea, or uploading settings from a PCC). What else? After looking for a while it looks like the market is pretty stagnant. No real developments, poor design aesthetics and features, no premium options...the joyetech eroll came out around 4 years ago - great design but plenty of issues. It seems no one took that eroll and improved it, even with all these years gone by. If you google 'best cigalikes' you'll be looking at years old technology. That is sad.
