Review on Greatergoods Digital Body Fat Weight Scale: Accurate Health Metrics & Body Composition Measurements with Large Backlit Display - Silver by Cody Simmons

Updated review 12/13/20: I have updated my review as following my previous review the seller was kind enough to send me a replacement scale without me contacting them directly. This shows that they genuinely care about their customers and believe in their products. The replacement scale seems more accurate to me, it still has some issues with different users who are a similar height/weight, but I just removed all the users and used it solely for myself. I think it's been over a year since they sent a replacement and it's still working great. I weigh myself weekly, and while I still don't believe %bf, bone density, water, etc. are even accurate, I use them as points of comparison. I've been gaining weight like crazy lately and the scale was pretty accurate on those numbers lol. In general I would recommend this to track how much you are losing/winning, but be aware that it is not 100% accurate. The weight could be 1 or 2 pounds less but it suits my needs perfectly. ORIGINAL REVIEW: Even at its best, this scale was always off by about 2-3 pounds, but that didn't really bother me. I assumed other measurements might not be as accurate, but they fluctuated as my weight fluctuated, so I just used them as a point of comparison and didn't worry too much about their accuracy. However, for the past year or so, this scale has given me the exact same weight every time I've weighed myself in at 142.6 pounds. I found it weird so I grabbed dumbbells or something heavy and tried again and of course my weight gained. However, every time I tried again at my normal body weight it would read one if I hit it at 143.8 and after it finished sizing or whatever it would bring me back to the same weight at 142 .6 pounds. I deleted all user profiles and still have the same problem. I've tried the scale at my doctor's and at the grocery store and my weight is 135.8 lbs. Where does this scale get these numbers from?
