My thoughts on original and fake stippling brush!
As you can see, there is huge difference in hair length. Original has nice firm short black and white hairs and fake has much more fluffier and longer white part.
Another thing is brush handle. Original has matte black part, and not visible seam, and fake is shinny plastic with obvious seam. Also ferrule on original is much better, holding bristle at place, and has a nicer edge while fake one does not hold bristle tight enough.
There is much difference in hairs as well as you can see, fake has much more density and while applying foundation all the hairs sticks and absorb enormous amount of product. With original there is no such problems at all, it blends foundation nice, does not absorb a lot of product.
One more thing that is horrible with fake brush is that when you lean it on you face all the hair tilt on one side and stay that way witch is one of the reasons why this brush leaves funny strikes on face, and you can't stipple with it.
I noticed that fake one losing a lot of hair every time I washed it, but didn't noticed that original lost any.
On RT brush I really like that bristles don't stick to each other, and when drying it doesn't lose it's shape, while with fake one I have to be careful and it dries with sticked bristles.

Overall this fake is not worth of that money at all and I strongly suggest you to save that money and buy original, or at least some better quality brush, because this one is not!
