I got the product free from a giveaway. And I'm kind of thankful I did.
Though I did find that when I took my time it did give me noticeable length (I have short, sparse lashes), and a bit of volume, because of the way the brush is, it took more than than I felt was necessary to spend on my lashes.

It does take a bit of time to get used to the dual brush concept, and really depends on finding which way works for you.

I did have to recurl my lashes after the initial application mainly cause it would undo the curler I did prior to it.

I also noticed an interesting smell, though not horrible.

I would personally stick to the Stiletto cause of the ease of use on my own lashes.

Annabelle's volumelash boasts 5x more volume. After just one application of the mascara, my eyelashes did look longer and thicker. I usually have to reapply a couple of times to get my lashes thick. It also stayed on my lashes the whole day. No black smudges in the corner of my eyes, no raccoon eyes either.

The application, half brush - half comb combination, did take some getting used to. But once I got the hang of it, it became easy. The best thing to do is apply with the brush, then comb to separate, then brush, then comb again.

Another con for me is when I first opened the tube, a strong chemical smell came out. I was hesitant at first to put something so chemical smelling so close to my eyes, but it went away after a while.
