I guess we bought these scales in the 1990s. They are electronic with a red LED display, common at the time. Over the years the set become inaccurate, giving higher and higher readings, which we were finding quite depressing. Finally it failed altogether, displaying lo battery, which was not rectified by replacing the battery.
We looked for some new ones. Ouch, anything between $40 and $120 or more. We tried Big Trouble U, and this neat and uncomplicated set made of white glass was $30. We took it to a self scan register, and it scanned at $20. Nice one.
Of course for $20, you can't expect it to be dead accurate. We both feel it is giving a too higher reading, but it is useful to know if we are adding weight or losing weight.
