This scale is very accurate and consistent for the past 3 years. Performance I have moved a number of times and the scale is always accurate even though I have done nothing special to protect it during my moves, other than place is on the floor board of the backseat of the truck. Durability It still looks new and when I wash it I just use a clorox wipe on it. It is a quality product. Ease of Use The scale records and saves all my data which I can easily retrieve. Accuracy This scale is always exact when compared with my Dr'd scale.
