Query: caution

This item is attractive looking but the one I received didn't work. It quickly weighed 4 pints of water as 4.6 pounds. Not accurate, but close enough for checking on gain/loss which is what we are concerned about. But the baby was another matter. The scale took much more time to reach "hold" and give a weight. It gave wildly different weights as we tested it over two days. The last weight we got at the medical office was 11 pounds 8 ounces. The sale gave the following weights: 11.4, 9.6, 10.38, 11.2. This is obviously of no help. Of course, the baby moved his arms and legs, but did not squirm and was not in distress. And babies do move a bit.
