I used to use one of the Loreal brands. I don't remember the name. I only remembered the shape of the container. Now, I use Estee Lauder's XL. I once bought Estee Lauder's MagnaScopic mascara that comes in a thicker tube because the XL was sold out. It worked great for making the lashes look more voluminous and plump. I have lots of eyelashes, I'd rather they look longer and more natural.
BTW, I'm not a big fan of MAC's mascara, any of them. It's too liquidy for my taste. I end up smearing it before it has a chance to dry. Also, it's not good to apply MAC while driving. ;-) Another pet peeve of mine... MAC's sales people are usually inexperienced, immature youths lacking in any decent customer service skills!!! I'd rather not have to yell my order over the music either.
