Model Co Fat Lash Mascara

I recently received the Model Co Fat Lash Mascara in the January Bellabox. Bellabox made it seem like the most amazing thing around. Knowing it wasn't waterproof, I knew it probably wasn't going to have an effect on my lashes, but maybe it could be usable on bottom lashes.
 

The wand reminds of me the Benefit They're Real mascara wand with the bristles at the tip of the brush, which I've always wanted to try. The brush is very thick though, it would possibly work with fuller, longer lashes, but for my sparse, short lashes, its really hard to get into the roots and I end up getting mascara all around my eye. It's a no from me, but who knows, it might work wonderfully on people with longer lashes.
