Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Colours as described and seen in the picture. I didn’t realise this doesn’t come with base and top gel coating which was my overlook so you still need to purchase those separately! Good combination of neutral and dark enough colours. Quality wise, it does the job!
