TANITA Baby Scale There is a crack in the display screen, but it does not affect the visibility of the numbers. I used it almost every day to measure breast milk intake until my baby was about six months old. I am selling it now that my baby is over a year old and I no longer need it. The battery life is unknown, but I will ship it with the batteries installed, so you can use it right away upon arrival. *There is no instruction manual. I will pack it in a box and wrap it in bubble wrap before shipping.
