I bought the Etekcity EB9380H, and its resolution is indeed somewhere between 0.5lbs and 1lb.
I’m fine with that, but less fine with Wirecutter making bogus claims about 0.1lbs accuracy and boosting that ordinary scale’s ranking on Amazon.
2022 update
The scale was useful to check that I was maintaining my weight while eating around 1700 calories per day and lifting 3x/week. Helped get in excellent (shredded) shape in spring 2021.
In 2022, I didn’t have a scale, but repeated the protocol of eating 1800 cal/day and lifting 3x a week. Since I knew my daily calorie needs, and that my body would undergo recomposition, a scale wasn’t necessary - as long as I did stick with calorie counting.
