The only vapes that seem to last for years are log vapesz and the two German ones(volcano,aromed). All the other ones eventually have problems that need to be sent back to the company for fixing. The log vales only have one to a few temperatures you can work with, and you have to do internal work for that to happen. Any other vaporizer that allows you to go from low to high and has a screen that allows you to see where you are at, I constantly see problems over the years. Something eventually goes wrong. This is for me though, because I don't like to use vapes that have a set temp unless I have to. For others there are tons of choices but I'm a healthut so iI have only a few choices. I need to be able to choose temperatures from low to high, have preicse temperature during the air going through the herb, not worry about offgassing over the years, need to have the vapor cool, and with very little particulate matter, and easy to fix if needed it or at least I won't have a problem replacing the heater, or other important parts.
Vaping is better when compared to smoking but, I'm not comparing it to smoking, that is a given. I'm comparing it to someone who doesn't inhale anything but air. I have seen too many people complain about respiratory issues when vaping for a while. Some don't know about this site so they won't be able to find help to deal with it. Even before this site, I would hear about vaping throat, and lung, issues.
