i am very impressed with this electric scale. It has a nice digital display and I have been using it for about a year and a half and I have yet to have to replace the batteries. The scale is very smooth upon touch with the feet and fairly accurate. You can also get on the scale in the dark since the screen illuminates once you step on it. The scale does have to be on a flat surface, the flatter the surface the more accurate the scale. When stepping on the scale it is important to make sure that you are properly balanced. I advise you to not place the scale near a source of water. Again I am impressed with this scale, it is simple and easy to use and it will last you a long time. I recommend this product due to its lightweight design and quality.
