how funny! yesterday i posted DIGITAL SCALE MELTDOWN. i would weigh first thing in the morning then step off and back on and always never the same number twice. so, i moved the scale to different tile surfaces in my house and again, never the same number.
long story short i knew i had an awful scale when i took it to the garage ( i figured the cement is as even of floor i was going to get). would you know it same thing
last night i went to target and returned my 89.99 digital and bought a 24.99 analog. would you know it i weighed 2 pounds less
i also tested it by putting a ten pound weight on it. i stepped on and off 5 times and got the same read every time
i think the digital have issues with the floor eveness and even how you step on.
