Query: I question the accuracy

My scale values consistency over accuracy. It does not recognize small (few pound) changes in weight in repeated measurements. It reads the same until "reset" by a significantly different measurement. I purchased this product several weeks ago and weigh myself every morning. I became suspicious when my weight was identical every day for a week (weight is displayed to 0.2 pounds.) So I weighed myself then picked up a 12 oz tooth paste tube and reweighed, identical total weight. I added my electric tooth brush, again no change. These two items should have added just under 2 pounds. When I grabbed something weighing about 5 pounds I got a new weight. I now cycle the scale with something light, wait for it to reset, weigh myself, then wonder what I really weigh.
