I like that it was fairly cheap, had good reviews and came with a carrying case. I lost my original digital caliper and bought this because it was supposed to be delivered the next day. My original was even cheaper, but when I just found it I measured with both things, like small drill bits. This caliper is way off (about 3-500 inches shorter) and my cheaper old no-name is very close. I think it's even outside the specified resolution range.
