It's easy to use, it has great documentation which makes learning how things work super simple! The support team are also really helpful when you have any questions or need help with something specific that isn't in their docs (like I did!). There aren’t many downsides - if there were we would happily look into improving them for our customers as soon as possible but so far everything works well enough without too much fuss required from us :) We're using helium scraper mainly because of its ease-of-use compared other scrapers out there such as beautiful soup etc., plus being able to do some data extraction ourselves rather than relying solely upon what they provide via APIs/RESTful endpoints.
