I've been using this brush every day for 5 days now, and I love it. I use it for all of my liquid/cream foundation, concealer, blush, highlighter. I'm thrilled with the results. I have not tried it with powder products, as I don't really use powders for much, so I can't speak to that.
As for liquids/creams, however, I love using just 1 tool. Very convenient, applies product evenly. It does shed a little, but not excessively...and a little shedding is normal when a brush is new.
