The amount of research I have been able to do using their library is incredible! They are really good at finding articles that you wouldn't even think about looking for themselves - but they still find them anyway so it's not like your search results will be biased by what other people know or don’t want others reading too much into this comment :) Their blog posts can sometimes seem somewhat dry if all content isn' very "sexy" as some would say however there aren;e any issues with quality either way which makes me happy when reviewing products online!
