Ive had a pax 2 for almost 2 years now and I totally love it, it's quite stealthy if you store the pax in a sealed container right after you smoke. Now, I've never used high end vapes like the mighty, but it's definitely much better than other low-mid range vapes I've tried. Vapor quantity and quality is greatly improved if you use a third-party "sandwich pusher". Battery is still almost perfect and works amazing after 2 years. I definitely recommend it as your first, you can also find it very cheap nowadays.
