Query: Worked great until it stopped working

I really liked this little scale, until it suddenly stopped working after 3 months. I don't ship a lot of packages so I'd only used it about a dozen times altogether. Tried switching out the batteries with fresh ones and ones from a working flashlight - no luck. It just died.Checking reviews for other scales by this company I see similar complaints. Too bad, because it was a nice product, while it worked.
