I own too of these, in the shades Peach Goddess and Ice Cold.
Both were very gorgeous shades, that I really loved - both are what the names suggest, peach goddess being a beautiful peach shade and ice cold being a gorgeous frosty white. They applied well and sat nicely on my skin. Both were super pigmented and I loved the way they looked.
My issue with these is that they broke super easily! Ice Cold shattered when I dropped it onto my makeup desk from not very high at all, maybe 5cms? Peach Goddess broke sometime in my makeup bag without me knowing, which has never happened to any other powders or palettes that I have owned. Both shades completely shattered and turned into an awful crumbly mess. Tried to repress both of them and just didn't have the same pigmented glow as before. Not sure if this is a common problem, but I was extremely disappointed, especially since I hadn't owned them for long. I haven't repurchased as I own a ton of highlighters and didn't want to risk spending more money on any in case I had the same problem.
This highlighter is very extreme, I have the shade ice cold and it works very well with pale skin tones but it is very blinding. I like a more subtle highlight and I can makes this work if I take a very light hand when applying. this is a very pigmented highlighter and I think it would be awesome if you are into that very blinding glow and even if you are not you can still make it work with less product. This shade is perfect for fair skin tones.
Tips: for a less intense highlight use a light amount of product on a fan brush and apply to your cheekbones. For a more blinding highlight use a crease brush and apply to your cheekbones, or even spray fix plus onto the crease brush for even more extreme highlighting
