I love these brushes and have been waiting a very long time to get them as we don't have them here in Canada yet. My sis-in-law went to San Diego and got these for me and I'm forever grateful. The buffing brush alone is worth double the price of the entire collection. I've been using it to apply my MAC Face & Body and its amazing. It buffs the foundation so well in your skin its as if you're using your hands. I'm really clumsy with applying makeup and prefer to use brushes over my hands if I can help it. I use the precision foundation brush for concealer and the contour brush for applying powder blush. I haven't really found any use for the detailer brush but have read that it works well as a lip brush and will try that out soon. I'll definitely be asking my sis-in-law to get me another set when she goes back to San Diego so I can have another of the buffing brush. Really awesome quality brushes for dirt cheap. Samantha Chapman is a goddess.
