This is my go-to mascara when i need nice, long and dark lashes. I was somewhat surprised when I saw all the negative reviews and comments for it. It's a good thing I saw them after I had already bought it, for it's the best one I've ever used!
Of course it has its downsides, such as the really big wand and it does have a tendency do dry a bit fast. When I use it every day, it lasts for about a month, which is a bit short. I bought it at the local drug store for about 15$, so I wouldn't say it's a cheap mascara but definitely not among the expensive ones either.
The upside of this mascara is that I get the most beautiful lashes when I use it. It is amazing how big of a difference it makes! I have no idea how it works but it's something to do with the two kinds of bristles on the wand (hence the "double" twist), one kind to make the lashes longer and the other (the silicone part) to make them more volumized.
Overall, it really is a good mascara for me and I am very surprised that others are so unsatisfied with it. I am reluctant to recommend it to others because of all the previous negative reviews, but I don't see a reason why it should make my lashes more beautiful, and someone else's not... I do warn you, though, it does dry out quickly, so if you don't feel like experimenting or spending a fair amount of money every month for a piece of makeup, I suggest you continue your search for the perfect mascara! As for me, I am sticking with this one for a while!
