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.
Love it! I’ve used an array of gel name brands that seem to chip after 2-3 days. The base coat allows the color to adhere properly and the top coat is actually pretty shiny which doesn’t dull after a few days of wear. Throughly impressed, I will def be buying again!
