Every d20 gamer loves feats, right? Well, if you agree, then this is a great product and you will drool over the vast array of feat paths presented here.
What it does: Iconic Combat Feats (ICF) presents a plethora of feat paths to make a hero unstoppable in combat. The concept will be familiar: you start with a feat, then make it improved, then advanced, then greater, and ICF takes this to about three more levels in many cases.
The good: more feats than you could possibly use. You'll want to create more characters just to start a new feat path you hadn't considered. There is a useful index of feats, named "Contents," at the end of the product. One very significant element of design is that most more advanced feat levels are divorced from previous advanced feat levels. This is easiest to explain with an example. Instead of having to have, say, advanced whirlwind attack in order to qualify for perfect whirlwind attack, you just need the normal prereqs plus enough BAB. This design element is vital because even an epic build could not have enough feat levels to gain each feat in a tree while taking other necessary feats. Unfortunately it can't be implemented across the board because some feats such as Dodge have already been officially sanctioned with full prereq path of advanced-greater-supreme.
The bad: there are two let-downs I'm sorry to say. First, ICF lacks a philosophy: a foreword explaining the reasons for using it and the design (above) would have been good. Lacking that may make it hard for GMs to decide whether to include all or part into their campaign planning, and hard for players to get their head around. Second - and this may reflect the very cheap price - it lacks a panel laying out these feats (with links) against the greater schema of feat building generally.
