I'm not gonna lie, this is great mascara, but I'm not crazy about spending almost $40 bucks on mascara. I don't mind spending money on a quality product, but you can get just as great mascara from Clinique or Lancome for way way cheaper.
Anyway, this mascara is very natural looking & gives you great looking lashes. I know some people love the new rubber brush, but it actually hurts my eyes a bit -- it's a little spikey. And while it does lengthen my lashes, it doesn't thicken them as much as I would hope. I think it's because it has a rubber brush instead of a classic, plush, "pipe cleaner"-style brush. Also, I find that I need to apply like a zillion coats to get the results I want.
Overall, a good mascara, but if you are broke & don't have the disposable income to spend, it's not worth it.
