The balance is perfect and works well. Be careful though to the manual that is not detailed enough, hence no doubt the comments of some disappointed customers. To measure your rate of fat mass, muscle, bone and water, you must: select your memo, do not wait until the number stops blinking and press "start"; properly position your feet on the metal parts of the instrument (and not on the glass plate) your weight will flash and a bar will appear at the bottom of the screen; wait 5 seconds and all your rate will be displayed!
