I actually thought this powder was pretty good until I discovered better products. The downfall in my eyes is that it doesn't seem to last, and I had to reapply a few times throughout the day.
It's a very light powder and it does set the foundation well, so I'd say it's definitely worth the money. I used this powder for quite a while until I decided to try the Maybelline 24 hour powder which I'm now using.
This is the first powder my mum bought me for my 15th birthday! It is a good product. it applies well and doesnt feel too heavy at all. However if you are in a place where you are going to be sweating a lot, it will work against you. It will clump around you nose, but you can always re-apply. Still a very good product
Tips: I would apply with a brush over top of liquid foundation as you're guarenteed to get better coverage and a smoother finish.
