I have absolutely nothing but good things to say about this powder. The price? A steal. The packaging is adorable and classic. The powder is a finely milled translucent shade that doesn't look cakey or leave a white residue. It also doesn't make my pores look bigger, which looking back, was an issue with the Maybelline loose powder I had used previously.
It is impossible to use "too much" of this powder, I put it all over my face and bake with it too, and somehow it doesn't cling to any areas or look ashen. Baking the undereyes with this is easy, I take the powder puff it comes with, fold it in half, dip it into a pile of the loose powder, then dab it along my undereyes and the highpoints of my cheekbones, under my cheek contour, and a bit on the Cupid's bow and center of my chin. It will mattify you GOOD, to the point where you may not need a single touch up in an 8 hour day, so if you are a dewy skin lover or a au natural type, this might be too much for every day wear.
For a long time I thought loose powder was loose powder, you've seen one you've seen em all, and boy was I WRONG... this blows other loose powders from the drugstore away (I haven't used Nyx HD in a while so I'm not sure how it compares to that one, but the others, yes), and gives the coveted Laura Mercier offering a run for its money. And indeed, that is a great powder as well, but for $40... hmm I'll stick with my Coty for the time being :)
