I don't know about anybody else but mine wont work if its to cold outside. And if your battery's are going dead you run the risk of getting the wrong weight as well.
Jup, experienced the same. The digital one I posted on the previous page doesn't have problems with cold. What I did with the other one is keep em inside at room temperature until weighing.
As for the battery problem. Change em regularly and double check with another scale last week. Can't go wrong then.
