I have been using this powder for years now and havn't looked back.
It goes really far, and applies easily. I use it to set my foundation.
The compact it comes in is handy with a little mirror. I do not however use the puff that comes with it as it makes it look cakey and is hard to apply. I always use a brush. The colour is great and blends in very well. Plus its cheap :)
I've been using this as a finishing powder over double wear and also on its own over concealer and I think it gives a lovely finish. It's not oily, it's not powdery and it sets my make up really well.
Even over pimples a bit of concealer with this on top neutralized the redness.
I purchased this as a cheap alternative to try instead of my Elizabeth Arden and I would definitely repurchase. It's not in a hugely flash container but it does what it needs to do. For the price it's fantastic!
