Best course on recommenders I've come across. Thorough explanations, and learning tool works fine, despite other reviewers seemingly unable to make it work (sounds like a personal problem to me!). Definitely worth the 10$ value, especially considering you receive a certificate.

This course is one of the worst courses I have taken, ever. Content is old, no slides, very limited explanation, the interactive coding tool doesn't work at all. It has the same or even lower value than reading an article from Medium and it costs you $10. I want my money back please.
