Pros
Small projects, easy to fit in
Cons
They have very low payment rates and the worst translation software ever. You are unable to search the document for a specific word, you can't go back into the document to make changes once a page has been completed and they block translators regularly if they don't deliver 100% which can happen easily as the translator does not have access to the client's file and only to a cheap machine translation of that file which Fairlingo puts into the software's source file. So if I get a project from Dutch into English, I only get a machine translation in English for me to edit into better English. They don't pay for translation this way, but only for revision, for about 0,005 cents per word. This obviously means that quality is compromised.
