This scale does everything it is supposed to do. I found that it was perfectly calibrated when I tested it against a set of calibration weights. I selected this scale because I needed a very wide range (this goes all the way to 6100 grams). I have found it to be very accurate throughout the whole range when doing multiple repeated tests and using the tare function with various containers and hanging fixtures. I would definitely buy it again, and Old Will Knott Scales has it at a much lower price than I found anywhere else.
