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.
Bought 2 of the 23inch monitors in white to set up the home office ready to start my Masters Degree. The monitors are perfect. Unfortunately dispatch and shipping was painfully slow and I had to send emails to ask why it had not yet been shipped within the 2-day dispatch timeframe as promised. Because of this they were late arriving.
