I am constantly on the search for my perfect mascara. Must be waterproof, lengthening, unspidery and great for sensitive eyes. Having thrown away £17.50 on a Clinique one last month I bought one for £1.99 in Lidl on Saturday. It is really bloody good and far better than the Clinique imo. So happy!!! It is called Cien Push Up and has survived since 7am including strong rain and a bath and my straight lashes look all curled and fluttery 
I have a Lidl nowhere near me (I was away with friends), so may have to spend £20 on petrol if my new mascara love affair continues.
