Not great... [SEP] I really wish I didn't fall for every beauty gimmick that appears and I should have skipped this one!  While the product itself is well made, it just doesn't deliver a flawless application like a sponge or brush.  Seems to just smear the foundation and leaves it looking streaky...I end up having to blend with a sponge anyway.  Seemed to work a bit better for concealer on my skin.  This is definitely not a replacement for your favorite sponge blender or foundation brush.  The only real pro is that it's very easy to clean...otherwise it  just makes a mess of foundation application.
