I have been using Benefit's Tinted Lash Primer for a couple of months now and I really like it on its own as a low key brown mascara. It's perfect for the office and quick, easy makeup routines. Certainly a lighter formula than the original They're Real mascara but it still adds a good amount of length and definition.
I realised recently that I'd never actually used it as a lash primer so I gave it a roll with Benefits Roller Lash.
