Thank you all for the suggestions!
ANOther - I know it's mostly accurate, cause it matched the dr's office and does keep going down. It just bugs me that it'll vary as much as 2 lbs, stepping on it literally one time after another. Exact same spot and all. I know it's not a big deal, but every little .2 down makes me happy so I like seeing them, lol.
cathydoe - I don't blame you! I'd rather not spend the money on replacing something I already have either. Particularly since I think I'll likely want one of the pricier models next time...
mrainy - You know, I didn't even think of that! Thanks! Mine is a Thinner brand digital also. I've had it for a few years, but this is the first time I've used it regularly, so I'm not sure if it's a new problem or not. Maybe it is time for a new battery...
