I love this product! I got the light because I have really pale skin, and it's the perfect cool toned shade for me. I usually have to build up the product a bit to get bolder contour I usually go for, as the product blends seamlessly into the skin (almost entirely so if you blend too much at first). However, I see that as a plus because you can really customise the level of pigment. My only complaint is that it's a bit more challenging to use on oily/dewy foundations, as the foundation can sort of cling to the stick - covering the contour colour and making it tricky to get good colour. The picture I attached features the product on my face after a couple of layers of the cream and set with a tiny amount of light brown powder.

I have very light/pale skin and purchased the lightest contour stick, which was suitable for me as I'm not into heavy contouring so it's a nice subtle effect. However those who would want more obvious contouring would need to buy a darker shade. Anyway, it's a very creamy and easily blendable product at a very affordable price, I use it almost every time I apply makeup. 

Lovely creamy texture, blends well, subtle contour

Pigmented, blendable and long lasting. Great value, great quality.

I have this product in both medium and dark - It very creamy, blends lovely and stays all day. I only use it every now and then though because a spot always appears after using it, and they only appear in the places I have put the contour (cheeks, top of forehead and jawline) - places I never usually get spots! Not sure if it is because of the oil in the product? If you want to use this product for the odd night out and don't mind a spot here and there then I would recommend... BUT if you want to use this for an everyday contour then I wouldn't recommend.
