It is a Blending Brush. If you hope to achieve a nice, clean, smokey eye, without the hassles of sponge tips/cutips applicator, then this is the brush for you. Can you achieve the same effect with other products/sponge tips/cutips, yes you can. Is it really worth the price...um not really. You can definitely find similar brushes by drug-store brands (Loreal, Sonia Kashuk, Elf, NYX, Coastalscents, etc). I got mine in MAC's holiday collection back when I had a MAC fever. It's been very useful, easy to clean up (i just use make up remover), didn't shed fibers, is soft and has lasted me the past whole year. Why did I give it 4/5, mainly because I very much dislike MAC's customer service, their attitude and most of the employees 'make up artists'. Would I repurchase this brush if I ever need to, definitely, but not from MAC.
