I found them great, i learned more from them than any of the other sources ive tried for time spent.
e.g 14 years school in Ireland, Rosetta stone, Irish classes.
There is a transcript http://www.gaeilge.org/pimsleurtranscript.html
I wish there were more lessons, or that someone would come out with something more comprehensive.
another great book and CD combo is Gaschaint, http://www.litriocht.com/shop/product_info.php?products_id=3883
it is a bit fast , but it has everything done in each of the main dialects which is great.
