The brush is definitely bigger than the other Great Lash versions.
For reference, you can see it next to some other brushes- To the left, is Maybelline's Illegal Length, which is about the size of a regular mascara wand. Great Lash Big is in the middle, and on the right, is Rimmel's Scandalash which is even bigger.
As for the results, this gave my lashes tons of volume, as well as some length. At first, I wasn't impressed, but I just kept building coats until I got the look I wanted. I was impressed by the fact that there were no clumps whatsoever, which made it really easy to keep building. On the negative side, it smudged under my eyes by evening.
Here's my before and afters-
The bottom line? This is my favorite of the Great Lash line! I never really agreed with all those people who said regular Great Lash was the best drugstore mascara of all time, but I'm glad I gave this one a try, because it's fantastic! Now, if they could just make it not smudge...
What have your experiences been with the Great Lash line? Do you like it or hate it? Which one of the three is your favorite?
