1938: Permanents. "Getting a permanent wave is "almost a national pastime" and the price has dropped to a dollar. But beware of shops that cut corners: "The felt pads between the curlers and her head . . . can be excellent carriers of scalp disease."
1945: Pudding and gelatin desserts. "These packaged desserts do enable the busy housewife to whip together a more-or-less tasty dessert in a very few minutes," we say. But that taste doesn't vary much. Anything colored red is equally likely to be called cherry, raspberry, or strawberry. And in a blind(folded) taste test, even some lemons and limes are mistaken for strawberry."
1952: Sunglasses. "We test 38 brands — and find 23 of them Not Acceptable."
1961: Car record players. "The needle of the Norelco Auto Mignon stays in the groove of our 45s, even when we drive over rough roads. But since there's no record changer, we must insert each record we want to play, then remove it when the song is over."
1973: Instant glue. "One drop of this instant glue formed a bond between man and hammer in five seconds. We called it an instant hazard—and rated it Not Acceptable."
