Does it Work? - WW Scale?

I picked up a new scale last night since my old one wasn't very accurate. I decided on the WW one. I'm not on the WW plan but the scale looked to be the best in my budget. Anyway, everytime I step on the thing I get a different number. It claimed I had lost 3 pounds in one day so I tried it again and it gave me the same thing, then again and that time it gave me 2 pounds higher. I always make sure my feet are completely on the scale and that I don't move too much.

Anyone else use this scale and have a problem? Should I return it or am I somehow using it wrong?

Scales should be on a flat surface. test your scale by placing say a 5lb bag of sugar or flour..something you know the weight of, maybe a 2lb dumbbell. try to weigh yourself at the same time each time. Also don't weigh yourself everyday as your body changes do to hormones, eating, water, stress..etc...I sound like a doctor do I? lol I am not,but that is how I weigh myself. I always test a scale..Have a great day.

Is it a digital scale?

my digital scale will show a difference of one or two pounds if I get back on it too quickly? it's not a ww scale, just a digital scale I picked up at walmart. it seems to be pretty accurate unless I get getting on it too quickly.
