Not exactly worthless. I usually assume that 1 and 5 star reviews are by competitors and shills, respectively, and mainly ignore the star value anyway. I read 2-star reviews first, and look for text descriptions of identifiable strengths and weaknesses, and these must be corroborated by other substantial reviews. If anyone, with any star value, says "I wasn't shipped what was advertised/listed", I just close the Amazon tab, and look at other retailers. I don't have time for counterfeiter roulette any more.
