Safeway not ayoba

I bought a safeway body weight scale, after using it for 5months it came up with an error, returned it to clicks had to choose a different one, i used it for 3 months it came up with the same error, returned the scale. I got a new one that gives incorrect results, i get up it gives a number, try again a different number, again a different number. Do you really want me to return it and get another problematic one? I dont think so. Safeway is not safe when it comes to quality
