If you want length, this is pretty good stuff. I got longer lashes with it than with any other mascara I have used. “Zoom” is certainly an appropriate name! The black shade is very black and the effect was quite dramatic. I also seemed to get a decent amount of curl from this mascara, which is uncommon for me even with mascaras that are advertised as curling.
On the downside was that the brush picked up a lot of the product and I had to be very religious with the wiping before use. Even then, I tended to get some clumping. To be fair, I do tend to run into clumping with many mascaras that have a large brush and/or seek to thicken lashes, and at times I think this is something unique to me. But I did also notice that I was wiping a lot of excess off the brush before use.
Overall, I liked the mascara because of the dramatic effect, as long as I was pretty careful with its use.
