I bought this brush because I wanted to see what kind of finish I'd get from using a brush with my foundation, and the price was right.
The bristles are soft, as they always are with e.l.f. brushes (5*).
After trying it out, I decided I prefer to use my fingers and a sponge. It wasn't that the brush made my foundation look bad, I just felt it required more effort to get virtually the same effect, and I'm lazy.
It could be I wasn't using it correctly, but I felt that I was using more product to cover less skin surface. Since I only require sheer coverage, it seemed silly. Maybe if I needed a more opaque application it would be good to use.
In the end, I still felt the need to use a sponge over my whole face. Old habits die hard, I guess.
I do find myself using this brush quite often to put a thicker layer of powder over my concealer when needed, and as a quick way of swiping a pale shade of eyeshadow over my whole eye. It's awesome for that, also for highlighting my cheekbones.
As a foundation brush, I found it silly, and wouldn't buy it again. As an "other" brush, it was well worth the dollar paid.

For foundation, this brush kinda sucks. The ends of the bristles are pretty blunt and hard. It makes foundation really streaky. You can make it work but it means taking 6-8 minutes to put foundation on and going over and over and over it with the brush to get the streaks out. Who has the time for that? It works okay to blend stick concealer, though. But lately it's moved to the back of my brush drawer and I haven't grabbed it since I got the Studio line concealer brush.

This is the brush to I use to apply my primers with. It is smaller than I would like for my foundation, but only $1!!!!! I have washed this brush more times than I can count, and it has no shedding at all. It is made of awesome quality for the price.

I bought two of these-one for cream blush and one for concealer. It is smaller than I thought (for cream blush-its smaller than Becca cream blush brushes) but perfect for concealer.

It did a good job for undereye concealer but was FLAWLESS for face concealer (different make) perfect and so cheap!

Better than the small concealer brushes I had that seems to scratch out concealer. This has a featherlight touch and it great to use! Glad I read the boards and reviews-this ones is a keeper!

Only a dollar??!
Asians rejoice!
This is a terrific brush for only a dollar, very soft, and it hasn't shed so far! Applies liquid foundation very easily and smoothly, all I need to do now is blend with my fingers.
Though the brush and handle DID come apart, it still holds a high rank IMO. You get what you pay for when 'Made in China' and a 1 dollar price tag come together.
Still though, a great brush for GREAT value.

I love this brush. I don't use for foundation though I use it for my primer and it does a really good job especially for only being $1. Just remember what you paid for it. Its not going to work miracles but it does a decent job.

For only a buck what? this is good brush i picked this up in manhattan as i was curious about it and its o.k. its not the lushest brush around and people keep in mind that you wont get department store quality take it for what it is and in my opinion its good value for money.

This is an alright foundation brush. Bristles are fairly soft but when applying foundation it may streak on occasions.

dirt cheap, soft bristles, puts on my foundation evenly, if you press too hard, it may leave a tiny streak, that was the only thing i didnt like, other than that, great brush!

I finally started using this brush, I bought it about 4 months ago..wish I hadnt waited. This is a great brush, and you cant complain about the price! I love that is makes my liquid makeup look flawless..I use this with my Revlon Colorstay liquid foundation, which everyone who uses it knows that it has to be applied quickly, but with this brush I dont have that problem..it doesnt dry my foundation out, it applys so smoothly! Love it!
