I bought this liner to replace an old Bobbi Brown gel liner I had. The price was right & the brush looked amazing to do a cat's eye look.
While the gel is the same quality as Bobbi Brown & the brush is a very nice size, surprisingly I find Maybelline's Eye Studio Liquid Liner pen much easier to control when usually it is the opposite for liquid & gel liners.
While I think the brush is great, it's just too hard to get a thin line with it & sometimes you can, sometimes not so much.
If you like to spend the time & you like a somewhat thicker line then I'm sure this is great b/c it is longwearing & just like most other higher end gel liners but I find the liquid pen the one I use for everyday.
