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.
It seems nice, well done but it has a serious problem... it is too short... people like me, with an 7.5 wrist won't be able to wear it unless they use the last hole and even so it won't be comfortable enough. The ad doesn't say it only fits people with smaller wrists... if you have a even bigger wrist... this is not for you. Cheers.
