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.
I like/love that I can get the tea, however at $20 above the 4-5 dollar one in the shop this was a one off. Bought three, so special days only. The containers are very dainty and strong. They all have great seals. See my other comments on other desasters.
