AMERICAN WEIGH SCALESDigitZ DZ Series Small Digital Scales Herb, Food, Jewelry and Kitchen Scale, Portable Travel Food Scale (Battery Included) 120g x 0.01g

A nickel is exactly 5g. I have another scale and no matter where I place it, it is ALWAYS 5g. This scale; however, is giving me anything from 4.95-4.97g. I requested a replacement the first time because even after changing the battery, it still only said 4.95-4.97g. The weight of a nickel doesn't change. So, it's clear that the scales are defective. So to have 2 scales that both show the wrong amount means it's the scales.
