I have been using this mascara since they began making it, I believe. I was already using the original Maybelline Great Lash mascara. I tried the curved brush version when it came out and have been using it ever since. I don't use it instead of the regular Great Lash mascara, but in addition to it. I always begin putting mascara on my eyelashes with the curved brush to give the lashes form. I know several women who use eyelash curlers. It makes my eyes water to watch them. Just using the straight brush can make my eyelashes point straight out so the curved brush helps curl them upwards slightly. My eyelashes are too short to use an eyelash curler and I don't think I could use one anyway.
After I start my lashes with the curved brush for form, then I use the Great Lash straight brush mascara for volume. After I finish my make up, I use the curved brush again one more time to give my lashes a little more curl and volume.
I like the fact that this mascara is water-based because I've used water proof mascara before and it is a pain to take off. Washable mascara is a must so that it can be removed easily without having to use a lot of pressure or lotions to get it off.
This mascara is not expensive and it works very well. I cannot say when I first began using it but it was so long ago that I don't remember. It just seems like I've been using it my entire adult life. I've tried other mascaras, even some that are fairly expensive, and I do not like any as well as Maybelline Great Lash. The curved brush really does help curl your lashes.
