Pretty pleased with this set overall so far. My only complaint is that in the accompanying book, the dialogues are very complex right from the get-go and get progressively more so fast. And the English translation is not printed line-for line-beneath the Irish. The English translation comes after the Irish dialogue, which often means a lot of page turning to keep track. And even when not turning pages, it is not easy to match. More of a drill at times would be nice, too. However, the intracies of the language, including grammar and pronunciation, are well explained, and that is much needed, as Irish is unlike many Europeans languages in many respects. The book is also well thought-out mostly, very readable and accessible, and the CDs very clear. I think if you want to learn Irish, this would be a good addition to your learning curriculum. You might like to include other sets as well, though. But I would always suggest MORE when learning a language. Think of how much work you put into learning English as a child.
Erin go bragh!
