I have a Tanita that I've had for years now, maybe ten. It measures to 0.2 accuracy and I love it. If I get wonky weights, it means I need a new battery. Everyday I diet consistently the tiny drop in weight is there (I weigh in the morning.) If I eat high sodium the day before, it might go up 2 lbs.
I weigh in at home in the morning before my WW meeting and am consistently 2 lbs heavier at the WW weigh in, so I am pleased with the scale and the consistency.
I've been on this journey way too many times
