Query: BUYER BEWARE OF HOMEDICS

I bought the SC510, wich is similar to this product, and it sucks. I didnt get a manual... They scale tips over or below your real weight if you shake/move slightly while standing on it... SERIOUSLY. I set some 20 pound weights on it and they read 17.2 lbs.... SERIOUSLY.... DO NOT BUY HOMEDICS PRODUCTS. ITS NOT WORTH IT , FOR THE MONEY..... WANT SOMETHING BETTER? BUY A DOCTORS SCALE.... THAT'LL WORK JUST FINE.
