Firstly, I'm glad the dialogues feel like conversations I would actually have. That makes it so much easier to relate to and remember.
Secondly, the explanations about appropriate politeness level are really helpful and put the different ways of saying things in context. I also like that the books tell you if a word or phrase is very common.
Last but definitely not least, I am impressed by the quality of these books. This isn't the first bundle by Clay & Yumi Boutwell that I've purchased and I will certainly buy more in the future. The content is consistently great. Even the files are well thought out with three different formats included for each book.
