I use a physician's balance beam scale. It does nothing fancy, and weighs only to the quarter pound. But, the battery never dies, and how much precision do you need? Your weight varies all day long with fluid intake and output, meals, exercise, etc. Weighing to the ounce or gram is just silly. You're insisting on decimal points for a weight that varies slowly all day and night long. Which one is your real weight?

Also, there's no point in having precision that goes beyond the device's
accuracy.

The common advice to weigh once a week is silly too. That doesn't avoid the individual variation. You'd be mathematically correct to weigh every day and calculate a 5 or 7 day running average. By the central limit theorem cell means are normally distributed so you could do statistics.
