Editing and formatting are top-notch, I didn't notice any glitches. Layout adheres to SGG's 3-column-standard and the pdf has no bookmarks, but at this length, the pdf needs none. While the product value of this pdf is beyond questioning and Guarded Attack is awesome to speed up high-level play, I felt nevertheless rather disappointed by this pdf. Seeing how great the idea of guarded attack is, I nevertheless feel like it could have been expanded via more feats, as I doubt the usability of the minor AC-bonuses - a greater variant of the feat would help here. Additionally, most of the feats felt like good ideas, but didn't truly wow me. Taking a look at my other reviews from the BP-line, I'll settle for a final verdict of 4 stars due to wanting more awesome feats, but finding no true problems.
[4 of 5 Stars!]
