Wanting to change the batteries because the scale does not work, a son that serves for connection of the son broke so suddenly a bloody balance after 4 uses. This is really outrageous. Besides the balance you hop on there, it tells you a weight, it runs you over you won 600 grams then you go back over there and again a different weight !!!!!!! The quality is not there and some should be ashamed to sell products like that !!! Avoid I lost my money
