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.
Not a smart TV (just the YouTube button doesn’t make a smart TV). Processor very slow (selecting any function takes a lot of time). No screen mirroring function as promised in the description . Also, this TV sold and delivered in Singapore, came with a European plug!!
