I'll start with the bad - throw away the sifter thingy in the top and the puff it comes with, they're rubbish. Also rubbish is the actual container it comes in, it's big, hard to open and close and just cheap looking.
Once inside however I find the product to be pretty good at setting my makeup and I have an oily T zone. Probably wouldn't recommend it for really oily skin over summer as it may not be heavy duty enough to last the day.
I like to apply this with the RT duo fibre brushes as they give a really light application, which is good as this powder will make you look paler esp if you don't blend it in well enough.
The best thing about this powder is the "blurring" effect. My skin looks quite a bit softer and younger after use, it actually helps tone down the fine imperfections.
So, thumbs up e.l.f, it's a good product that I can see my self repurchasing.
I bought this product after I had read so many great reviews about it, but I don't feel that it's as great as other people have found it. It does help if your foundation is a little bit too dark, as it is very white. It is very affordable, so it's not all bad. I find that it does the job for me, but is a bit difficult to get out.
Tips: It is easier to apply with a brush, rather than the applicator that comes with it.
