Produced I use for molecular cuisine. the balance filled his role well. it is very easy to use and accurate. The product's overall quality is correct even if the keys do not seem very strong. It comes with a carrying case and a hard cover to protect the tray. Its main advantage is its precision and 0.01g Max Supported load that is very important 300g It comes with batteries that (strong point) are not button batteries taken out but AAA. The report / quality / price / Precision're pretty good
