Mines come and I've tried it. As I mentioned previously, I ordered 5 as a corrector and 6 as a concealer. It's incredibly lightweight; I can't feel it at all which I'm astounded by. The 5 for me covers most dark circles but not all, but mine are bad and perhaps I need another layer or a thicker application. Both the 5 and 6 work so well on me (I'm a 7 in the foundation). Some did settle in fine lines, but I buffed it out with a brush very easily.
The brush is excellent, however I would warn you it's not as dense as it looks. Now that works perfectly for me, and I think for the thinner skin under the eyes, but if you're looking for the denseness of a brush like her foundation brush, this isn't it.
As for the olive, I like it. The box is olive too, and the brush box is a deep aubergine colour. Like others I expected gold as that's been her brand but I'm not against it. Olive is a fashionable colour of late, so it makes sense she's wanting to change things up.
For those who have bought more than 1, the numbers are on the bottom so you'd have to remember which number is the corrector. And either I'm old, or the numbers are small. This is very picky of me, and the shades look different enough side by side to tell which is which. However, I thought it worth mentioning in case of anyone who is perhaps a little tired in the morning or those who are short/long sighted (I can never remember the difference).
Interestingly, in using this I have noticed bags under my eyes. Now I may have had them before and just not noticed, or it may be down to some weight I've lost in the last few months. I understand why it's luminous, however I will always mattify this product with powder when using it under my eyes as a result.
In short - for anyone on the fence, just do it. You won't be disappointed.
but the product looks gorgeous
people won’t know me! Who is this youthful, bright-eyed creature, they’ll think? 
means I won’t mistake it for anything else when grabbing it out of my makeup bag.
