Bests & Worsts Reviews from Amazon

So the scale looks nice and I liked how some reviews included weights and measures. I disliked how others said the scale is crazy incincsistent. Well I bought one and it is extremely inconsistent. I weigh around 240. Step on this scale 223. Step off and back on 241. Off and back on 238. Off and back on 190. Move the scale 234. Off and on 228. Move the scale ... you get the idea. I was giving it 5-10 seconds each time before stepping off and back on. I also let the scale sit for three hours at one point and it remained uncalibarted. I did put a 50 pound dumbbell on it and it weighed 49.8 pounds. Two 50 pound dumbbell weighed 99.8 pounds. So this is probably a great scale for weights and skinny people. But if you have some poundage on you, my experience is hat this scale sucks. I am returning it.
