This balance would be perfect if the batteries do not even wore out when not in use: a set of 2 AA batteries each month, the balance is used or not. Only way to avoid this anomaly is to remove the batteries after each weighing and replace them before the next weighing. Not really handy !! The SAV importer ( [email protected] ) Has not responded to the statement of anomaly and request replacement of the article. Fortunately, Amazon.com was a copy for info responded and offered reimbursement of the unit. Congratulations Amazon.com!
