As many other before me have said, I got hooked into this product as a teenager thanks to it's reputation as being a "classic", plus the great price.
Very good for darkening lashes, however I don't think it enhances length or volume at all. If you are blessed with long, think lashes then sure but if you want anything other than colour changed I wouldn't go here. Also it tended to flake off my eyelashes by the end of the day.
This mascara used to be my go-to mascara. It has a good brush, and the actual mascara doesn't dry out in the tube so it lasts for ages (even though I know you are supposed to change your mascara every month or so, I don't!)
It does however get a little bit flaky during the day. I now use Jordana Extreme lash as it is 1/4 of the price and I actually like it better!
