I have tried all 3 so these are solely my own opinions, also I just want to point out that these are just how these mascaras performed for me, the results may be completely different for yourself but this is just an indication of what I think (phew got that bit over with)
Benefit have 3 mascaras: BadGal Lash, They're Real and Roller Lash.
BadGal Lash is the cheapest at £17.50 and the other 2 are £19.50 and BadGal lash comes in black, brown or waterproof black.
"They're real! lengthens, curls, volumises, lifts & separates. Our jet black, long-wearing formula won’t smudge or dry out. A specially designed brush reveals lashes you never knew you had!"
"Sexy, sultry, pure unadulterated black mascara for full, voluminous lashes. It's as BAD as you want to be! Famously big, bodacious brush coats lashes with our super black formula."
"It’s a roller for lashes! The eye-opening Hook ‘n’ Roll™ brush grabs, separates, lifts and curls…while the instant curve-setting formula holds for 12 hours."
In terms of Packaging I prefer the roller lash and They're real as they just feel a bit more high end and look a bit different. Where as I personally feel the packaging of BadGal lash lets it down slightly.
In terms of product I would have to go with the roller lash purely because as well as lengthening it really does lift and curl the eyelashes which allows me to skip the eyelash curling step in my daily routine. This mascara also stays put for a long time.
They're real works really well at lengthening eyelashes however it is quite tricky to remove. I find that this one acts like a waterproof even though strictly speaking its not.
My least favourite would probably be BadGal lash. Although it works well as a mascara for me the wand is just too big and I find that its harder to catch the smaller lashes towards the edges of the lash line.
I hope this little review type post was useful
Until the next time
