Sounds like it's better for you than Adderall but I wouldn't want to take it purely to work harder / faster / better. Unnecessary, prolonged brain chemistry modifications sounds scary, and the 'no negative mental side effects' theme from the marketing is BS (from 10 min of Googling).

Indeed; modafinil has quite a few side effects, at least according to a quick Wikipedia check (https://en.wikipedia.org/wiki/Modafinil#Adverse_effects) (and while Wikipedia isn't the most reliable source, at least they bothered to cite their claims, so I'm more likely to trust that then some unfinished marketing site).
