Benefit Roller lash mascara review

I ordered this lovely product as one of my valentines presents and it finally came yesterday. Its not out in stores till 26th Feb, I think but its available online on the benefit website. It is £19.50 and £4.00 packaging. The most I normally spend on mascara is around £10-£12, I normally use Rimmel London Retro Glam but lately my eye lashes have been a nightmare. They cross in front of each other, they're in my eye line and I kind of have this thing with my hands, if i'm bored and have nothing to do i'll sit and pick my mascara off and go and re-apply over and over again, weird I know. I literally love my eyelashes, they're fabulously long and i've never had to wear false eyelashes, i'm just hoping i've finally found the perfect mascara. It wasn't till late last night I realised my Roller Lash had arrived so I couldn't wait to use it this morning.
