hello!
they're the same company, I don't know why they're sometimes called BE and sometimes BM!
I think it's one of those products that you have to try for yourself, lots of people completely swear by them, other hate them. Personally I found the fdn faffy, made me look shiny yet powdery at the same time and made my pores look HUGE! I also found it took far too long to buff in especially compared to Laura Gellers BnB which takes seconds.
However, I absolutely love the original mineral veil as a finishing powder, makes the skin look airbrushed and flawless. Their blushes are lovely, very pigmented although some can be a bit sparkley. The eyeshadows are just gorgeous, very dramatic especially when used wet, again some can be a bit sparkley. I don't recommend the bronzers or tinted veils, far too shimmery (for me anyway!).
