This product is cheap and seems to work very correctly: weigh objects under 50kg with an accuracy of 50g I use it to weigh luggage or bikes. I appreciate its ergonomics: the handle does not hurt the same hands for heavy objects weighing. Selectable unit between kg and Lb (pounds). The weighing display freezes after a few seconds, making it convenient to store the measurement. Its use is very simple. CR2032 included and easy to change if necessary.
