Review of Sigma F80 Flat Top Synthetic Kabuki (was SS197) by swolf123
It's pretty good, but I don't think it's worth all the raves. I used it for about 4 months, and while my technique might not be as perfect as some others, it didn't always give me a streak-less finish. It also shedded a bit.
I was all set in continuing to use it, since I liked it well enough, but then I found Shiseido Foundation Brush and I quickly discontinued using the Sigma. The Shiseido brush is much stubbier, but it provides a more flawless finish and it has never shed. It's also much more soft. For reference I've used the following foundation brushes/applicators and probably more I can't remember: Bobbi Brown, Giorgio Armani, Mac, Smashbox, Sigma, Laura Mercier, Beauty Blender, Koh Gen Do, & MFU.
