Here are my thoughts on it!

From what I've used of it so far, this is the best crease brush I've been able to find and for the lowest price. It's $3, and I was able to find it at Target, so I saved myself the cost of shipping, yes!
Its small size makes it perfect for precise crease work and that "outer v" area of the eyelid. For comparison, I pictured it next to the ELF $1 Eye Definer brush and the Sonia Kashuk Crease brush. The Sonia Kashuk brush isn't a favorite of mine because of its roundness and larger size- it's almost too big for my crease. The Studio Contour brush is small enough so it places color exactly where I want it. It's also a little more pointed than the SK, which is really rounded.
In an ideal world, I'd have the Contour brush pointed like the MAC 219, but that's probably asking too much for $3! The 219 has been on my wishlist this past year for its precision and ability to apply color to the lower lashline. The ELF Contour brush is too rounded for the lower lashline, but it's still perfect for those of us with smaller creases or more deep-set eyes who just don't like doing too much in the crease (like me!).
The synthetic bristles are firm and dense, which allows for more control. They also pick up color well- I like to kind of "roll" the brush into my eyeshadows. I find this picks up color the best way.
I've also given it one quick wash, and no bristles came out.
If you've been looking for a nice, quality crease brush that's inexpensive, definitely take a look at your Target for this one! I'm really impressed so far.
Have you tried this ELF brush? I'd love to hear your thoughts!
