High-tech balance

The balance SMS500 has a neat appearance.
It works with 4 AAA batteries normally included in the product, as the copy I received.
It's a memory function in balance: it can recognize up to 8 different people. Simply step on the scale, wait for the weight is displayed and it flashes 3 times: you are then stored in the memory of the balance.
Therefore, the balance recognizes the user when it goes on top: after 5 seconds the previous weights are displayed and color changes according to the evolution. If the person has lost weight, the light is green, if the person has taken, the lighting is red.
There can clear the balance memory as needed. In addition, an adjustment function lets you choose between 3 different measures: mine was calibrated in pounds, I had to return to kilograms.
