This is the second time I bought this scale. The first one only worked for 2 days. Thought it was a defect so I exchanged it for another. What a mistake. I have had the 2nd one for 1 1/2 months. It is not accurate. The scales went up 7 lbs one day, hours later down 4,up 2lbs the next time. I can step on it 10 times in a row and never have the same number twice. It will move between 1 to 5 pounds. When you are watching your weight you want to know for sure, if your weight is up or down, not spend 15 minutes every morning trying to get an average number. I am very dissappointed that weight watchers even put their name on it. There are way to many scales with better feedback, Please dont waste your money on this one !!!
