This very attractive small scale SEVERIN kitchen is delivered in kit .We are far from the assembly complexity of ikea furniture since the content of the box is limited to two rooms: -the electronic scale silver plastic -its glass top of a little less than 16 centimeters in diameter This one is fixed to the unit by a screw requires using a small Phillips screwdriver not included (but everyone should have one, right?). A flat battery 3V lithium battery (CR2032) is included, which is a very good thing, but strangely, housing is destined to receive an ample size to accommodate two 1.5 volt LR03 much cheaper and much easier to obtain: I'll withdraw a star for that questionable choice on the part of the manufacturer (the flat batteries are also more polluting for the environment). Regarding the use of the machine, it's very simple: an on / off button, which also allows to force the display to zero (setting up of an empty container) and a selection button the measurement unit (ounces or grams). For demanding amateurs, I said that the resolution of reading is 1 gram weight, which I find more than enough in a kitchen (receipts indicating the weight in milligrams are rare ...). I recommend this beautiful object acquired for just under 20 through AMAZON.
