Benefit They're Real. Retail around 20 quid. Don't be tempted by eBay around 7 quid as they are fakes. I bought one and knew something wrong as light as a feather. Got refund from eBay. Good feedback is given on most of these cheap ones as people don't know any better. A few do though! The real product is really excellent.
Interesting answer from grasscarp as I bought Benefit They're Real on a plane yesterday. Tried it this morning for the first time and have to say I'm impressed.
On my way back from Menorca, it was an impulse buy from the duty free brochure . It was only £16.50. I asked for it and as I paid the attendant said she used it and it was really good.
I tried the Benefit mascara...it made my eyelids itch,and was very clumpy. I got it from Boots.
Eyeco(available online) is expensive but very good. I currently use discontinued Define-a-Lash by Maybelline...long,separated,clump free.
Depends if you want build-up fibres in it. I don`t like a lot of fibres because I wear contact lenses and I need waterproof, smudgeproof mascara for work (so that I can nap during my break whilst wearing it). I tried many and the best one I found was from Boots Natural Collection for £1.99. Price isn`t always a good indicator of quality.
