I have been looking at both of these brushes. The Brush Crush is $145, the mini one is $59, the Instyler is $59.99. I was in Ulta today and asked a sales rep about the Drybar mini and the Instyler, she was no help at all. I do think I would get the full size Drybar if I were to go with that brush. Has anyone used either brush, what are your thoughts?
