300 x 0.001g 1mg High Precision Laboratory Analytical Digital Balance Scale Digital Electronic Scientific Lab Instrument Precision Weighing, Accuracy Weighs Grams or Ounce with 200g Calibration Weight

Probably one of the cheapest scientific scale of the market, accurate and pretty practical. Completely stopped working after a year with no warning though. Customer service never answered or advise me once the purchase was done or when I needed. Good scale for a back up, I would not advise to rely totally on it.
