I really like the brush, it's a soft rubber and it's really nice to use.
I almost always avoid any waterproof mascara since I've had bad experiences with it in the past, and unfortunately this one is no exception. It is really too stiff, and it flakes off in little bits that really irritate my eyes. I tried it a few times to see if it got better, but it didn't and I ended up having to remove it. I wish I got what I ordered, cause I really can't use this. I wonder if I'm even missing out on anything in the regular version, since I didn't get much curl with this even when I did use it. I still like the brush, it was easy to get to most of the lashes.
