Ok I have used this a number of times, so I think it's time to review:
This mascara will go against you if you apply it normally. I had to completely change my mascara application technique to make this work like it advertises.
Old technique: The good ol' wiggle at the roots and swipe. Yay lots of volume!
NOT with Lashblast.
New technique: Open. Gently "roll" brush on a tissue. Why? Because of the FATTY brush and odd shape, there is A LOT of product on it. Too much product equals clumps. Avoid scraping/rubbing, that will get tissue fibers all over the brush. And if you put the brush back in, there will be more clumps. (I hate doing this btw, so much wasted mascara

)
Now... do not wiggle at the roots! Yes, everything says that it give volume, but with this plasticy brush, it will be a mess. Ironic huh. So position brush at roots and swipe. Swipe swipe swipe until you're satisfied.
It certainly made some lashes I didn't even know existed pop out. Andddd.... yeahh...
4/5 stars. 1 star off because I had to figure out a new way for this to work.
