I have a new Clinique one and it is brilliant! It's called High Lengths. It has a very strange looking brush, but when I used it I just thought 'genius!'. It's great. And no flaking off that I have noticed so far. I was going to buy the Diorshow but it had only average reviews on MakeupAlley so I went for Clinique which had better reviews on there.
Will watch this thread with interest as I am Always after the 'perfect' mascara.
