I don't really find this blot powder very good for oil control, but it's one I come back to time and time again so it must have something going for it!
Firstly, even though it's virtually transparent in coverage, it's good to have the different shades available. I am NC43-ish and dark suits me perfectly, however medium-dark (which is what I was originally recommended) looked too light, even with the tiniest of applications.
The finish looks gorgeous - it sets my makeup and fills in the pores on my nose, but after a few hours the shine really breaks through and I'd much rather blot with a paper than reapply, unless I'm busy and on the go.
However, I love the compact, it's small and light enough to fit in any bag, especially small evening clutches. It's perfect for touch ups when you're on the go. The mirror is great, the only downside would be there's no separate compartment for the puff, so it gets quite dirty and oily (considering the nature of this product, you're applying it directly onto oily skin!), but to have a separate compartment would add bulk, so I can live with it.
Overall, it's handy to have in your bag if you're a busy girl. You can swipe this stuff on and not worry about it looking cakey and obvious if you don't have time to buff it out. It's not the greatest for oil control in my opinion, but with a great compact size and good shades, I'll stick with it for a bit longer.
