I'd rate this as the best ICONS supplement to date.
Most of the nitty-gritty is already available in other reviews, so I'll just mention a few points I found interesting.
1) Mr Tondro's writing is informative, entertaining and reasonably comprehensive. I haven't broken out my finetooth comb yet, but so far I haven't spotted any typos.
2) Mr Houser's art is, as always, very well suited to ICONS. For those who don't know, Mr Houser is also the artist for the ICONS core book.
3) The layout is clean and easily legible.
1) At $7.95 for 75 pages (the last two being Open Game License legalese) and the rest being relatively large text, it tips out slightly over my usual 10 cents per page maximum, but not by much. Considering ICONS itself, as of this writing, is on SALE for $1 and has 72% more pages... Still I'm reasonably satisfied, as the content is definitely of excellent quality.
2) My only real annoyance is that this Secured PDF not only lacks bookmarks (really silly to miss, in my opinion), but doesn't even have SEARCHABLE TEXT, making jumping to the page you want much more difficult than should be necessary.
For a Vigilance Press product, this book is slightly light on Nazis. Of the ten sample characters, they only feature prominently in the write ups of the Eagle, Victor, and Wundermaus (think Danger Mouse meets Nick Fury). ;)
I like this product a lot and I'm looking forward to the rest of the volumes in the series. It would be really nice, however, if the folks at Vigilance Press would kick up their efforts slightly and include both BOOKMARKS and (I can't believe I even have to mention this one) SEARCHABLE TEXT.
[4 of 5 Stars!]
