I bought this polish from what I assume is the new Essie diffusion line at Boots recently, and I was pleasantly surprised by the formula and brush. Sole Mate is a blackened red, almost plummy shade and was fine after two coats. It could even have been ok with one ticker coat, but I prefer to do several thinner layers. The brush is flat, and really quite wide, which can take some getting used to, but once you are used to it it's really quite nice and gives a really smooth finish. Removal was without problems.
