***PIC INCLUDED***I love this brush! I use it for buffing in loose powder and it works like a dream. Its dense yet soft, absolutely no scratching from this one. Also, NO SHEDDING ^_^ It is smaller than other kabuki/buffer style brushes (since its meant to be a blush brush, aye?), but for me that works out fine since I can get around my nose, etc really easily, and it still works well for large areas like cheeks, forehead. It really helped to set my foundation and powder in and minimize the appearance of pores, giving a really nice and even appearance to the skin. Also, it has a long handle which means I can store it with my other face brushes and not have it get lost in the jar, or have to have it out by itself on the counter (not sano!). Errrrm, all in all, I'd say a great brush...I don't use MMU but if you do, I would expect you would want a larger brush than this one for that (I use cream foundation and use SK's highlighting brush for that, covers more area so no chance of blotchiness), but for powder (and I imagine blush!) I really like this one.
Here's a comparison picture to maybe give you a better idea of size...the skunk and clinique blusher look funny because I just washed them o_O
