When I first used this mascara, I was a little put off by the curved brush. It definitely took some getting used to! But now that I've got it down to a science, this is the wisdom I can impart:
1) Apply this mascara before the rest of your eye makeup. That way, if there are any mistakes or smudges (which there will be!), you can remove them without messing up your entire look.
2) Make sure the concave part of the wand (hint: the curve that goes inward) is the one that grips your lashes.
3) Apply in the middle of your lashes first, as this is where the wand will grip easiest. Then use the end of the wand to apply in the inner and outer corners.
4) Apply thickly -- it won't clump, and you'll only have need for one coat!
My overall impression? My lashes are long, thick and voluptuously curly without the use of an eyelash curler -- and it lasts all day! If possible, it looks even better the longer you wear it. One last word of advice: Really take care to remove it well at night. If not, you'll find little flakes on your pillow in the morning.
