Hmm I was going to suggest the Renpho. Have you tried replacing the batteries?

I have been using a withings scale for a long time. I would not put too much stock in the body impedance fat percentage sensor, though it is sort of useful for trending. The weight measurement is useful.

Bonus: I also use the scale to confirm bags are not overweight for air travel and also to confirm packages are within certain weight limits.

Hume which also measures your fat and muscle ratios which is good info to have.

check out withings. mine measures everything and automatically syncs to my phone for long term tracking.

I have a Renpho, well rated, scale purchased about 6 years ago. Lately it gives me varying weights all within seconds/ minutes, up to 3 lbs off each time.

I need a decent scale and one that does other calcs- body fat, fat mass, etc.
Any recs?
