The list doesn't lie about the calipers being plastic but damn it doesn't put you on something that cheap. I have many carbon composite tools that give good mileage for the money on thin metal. For a measuring tool with such advertised accuracy, that's really disappointing: the jaws have side-to-side play, and I'd be concerned about wear and chipping over time. In terms of accuracy, I wouldn't trust them by less than 10ths of an inch - if that's the case. received two - big mistake, they are going back, and I will take a metal caliper every day.
