This course is good for those who are skittish about language learning. Portuguese is a language that must be heard to pronounce. The two presenters do a fair job at covering grammar, vocabulary, and culture in a fun way. Like all audio courses, this must be reinforced to really learn the language. If you're a grammarian, then a good grammar book will be more than enough. For many, the relatively new (and free) Duolingo will serve them better.
The price recently dropped for each of the Portuguese courses, making them a real bargain. Sure Pimsleur or Mango Language audio courses are good (and maybe a bit better), but at this price you won't feel like you overpaid.
