I'm really impressed by this brand. I used the quiz to find my shade and had it sent with a concealer. I found that the shade was very slightly off. Not so much that I can't wear the foundation, it's just ever so slightly a bit to yellow for my complexion. So I emailed and asked about exchanging it for something with a tiny bit more pink. They said that not only could I keep the original one, but they sent me a brand new foundation (they asked me a couple more questions to find the right match), as well as a $25 AUD gift voucher which I used on a powder contour. The new foundation is perfect and I love the contour as well. I'm really impressed by their customer service and I'd definitely buy from them again.
