I feel compelled to leave a review to help inform others who like me may hesitate to purchase this based on the poor review of another customer. To some extent they are right and their review is very useful for those who need precision: this is not a reactive, sensitive scale. If you need to be absolutely, 100% certain that you have weighed 15.4g of coffee (and not 15.5 or 15.3) for your espresso shot, this is not the scale for you. However, if like me you just need a cheap scale that is accurate enough to measure a dose’s worth of coffee beans, help make a good cup of pour-over, and can keep time, this scale is completely fine. It’ll do the job.
