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.
Great sound from a compact speaker. Good as a mini speaker and Great when use as a stereo pair with another One. Have One in each room and stereo pair in my bedroom. Humidity proof means I can shit and shower with music that I have them in all my 4 toilets! No regrets!
