Has anybody bought ''Fake'' Bobbi brown brushes from ebay?

I saw my friend today who bought a whole set of fake bobbi brown brushes from ebay and I must say they seem great! I own a few of the real ones and there seems to be no difference in quality the fakes may even be slighly better. She has not washed them yet so I don't know if they are worth buying. Has any one bought some them? How where they after you washed them? Thanks
