I'd stay away from tanita i have the hd332 which are s**te! They started weighing the same as CDC'd then they weighed 3lb's heavier then, overnight, they decided to weigh the same again! Useless! They give Err messages all the time too.
Mine have now totally died and just wont calibrate at all, all they say is Err.
Never again. I think i'll get some salter or weight watchers ones now!
