I quite like this. My last favourite was the YSL Everlong for day/natural looking lashes, and the Lancome Fatale for night (always requiring the lashes comb).
As background, I have incredibly straight, short Asian lashes, which wilt very quickly after curling. One of my favourites in the past was the Tarte Lights Camera Lashes mascara - this, like the Everlong, have a tendency to fan out the lashes, so that they look like BAND of lashes (which is what makes lashes sexy), as opposed to clusters (no matter how thick or curly) which most non-comb-brush mascaras produce. However, Tarte (while great for dramatic OR natural lashes) is hard to purchase here in London, while the Everlong creates pretty natural lashes so is not really suitable at night.
Iconic in black is a very dark black. The brush is in a "club" of combs (think of a round hair brush), just like the Everlong's brush. The only difference is that the Iconic's teeth aren't aligned between rows. What this means is that the Everlong, when you rotate it along the lashes, willl just roll and comb out clumps - whereas with the Iconic, clumps tend to get deposited BECAUSE of the teeth not being aligned. Because the formula is quite soft and thick, it fans out your lashes as very dramatic bands of dark lashes (although not as well as the Everlong), but it also means that clumps are pretty common, and these clumps, unlike drier formulas, can sometimes make your lashes stick together between lids as you blink (a bit annoying when you are on a date or something).
WEAR: In terms of wear, this is exceptional for wear (some mascaras fade over time - esp at night when you least want them to!). In terms of smudgeability, it lasts 9-10 hours quite well but does smudge after 12+ hours. (In this regard, this is far superior to the YSL Faux Cils - which gives the same level of thickness - albeit still in clusters instead of bands of lashes - but which smudged even after just 4-5 hours of wear). It can be hard to clean out entirely (ie still leaving a trace) even with cleansing oil.
CURLING: In terms of curling power, this did NOTHING. It lifted my lashes a little bit (hardly what you'd call curling, though), but so did the YSL Everlong. If anything, the Everlong curled MORE despite not being advertised as a curling mascara. It may have been the application - I find that with most mascaras, the trick is to apply it slowly, lifting the lashes as you go along - when you do this slowly enough, the mascara dries while the lashes are still lifted and so would stay that way for the rest of the day. This is preferably done with a comb brush like the Iconic or the Everlong, which would allow you to twist the brush as you lift, fanning the lashes out. Nonetheless, very few mascaras do much more being lifting on my lashes, so I will overlook this.
Of final note, this was the ONLY mascara on the market that makes my lashes grow longer than Everlong. Everlong was advertised to contain nutrients to make your lashes grow faster - and it did, but Iconic makes them even longer! Part of it must be due to the softer/more moisturizing formula, but I have tossed the box so can't tell whether it's an ingredients thing.
Overall, as long as you can spare the time to comb out the clumps, this is a pretty good mascara. Not HG just yet - still awaiting for some company to make that.
UPDATE: One great application tip is to use the tip of the brush to "draw in" the lashes first, as that deposits enough mascaras for volume. Then, to distribute the mascara, it helps to apply the mascara on the top of the lashes first, before applying it from the bottom. This way, the 2 applications "comb out" the clumps from the tip, but still maintains the volume.
