Thanks for the review, mikeperez23.
I also won a free sample but was so disappointed with my first wearing of it that my interest in IE promptly ceased. You've already mentioned a lot of good points (especially about not being able to detect certain notes that were originally expected to be 'noticeable' in the composition). Here's a couple of observations:
1) I expected IE to be exactly what it claimed to be - an incense scent with balls (after all, that's why the word 'extreme' was used, right?). Instead, it's probably lighter than any of the CdG incense offerings (but it's an EDP?!!!). I totally agree with mikeperez23 about IE being more suitable for warmer weather, since there's no way you'll be able to detect this on your skin during the harsh winter months. Sillage is moderate, longevity is about 4 hours max.
2) It pretty much smells like a CdG Incense reject (but less synthetic) - I would even go as far as saying that it's TOO similar to Avignon. However, because my recollection of Avignon is vague, please take this point with a pinch of salt. In short, if you own Avignon (or something else from this CdG series) chances are you won't be needing IE.
Now, I really admire and respect Andy Tauer, and am still hopeful that he will eventually release something as original, long-lasting and astounding as L'Air. Unfortunately, Incense Extreme is definitely not it.
