A plain, low cost glass scale with a long warranty; maker specs are the only evidence.
The short version
- People who want a simple weight only scale with no app or setup
- Anyone who values a long maker warranty on an inexpensive scale
- You want body composition readings, multiple user profiles or phone syncing
- The scale has to sit on carpet, since Conair says it is most accurate on tile or hardwood

What it does
A basic digital bathroom scale with a tempered glass platform that weighs up to 400 lb; the exact 2016 Weight Watchers by Conair model is unspecified, so this page covers the current WW by Conair digital glass scale that matches the original listing.
- Step on to turn it on, and the display shuts off by itself after several seconds
- Tempered safety glass platform with a 400 lb capacity
- Large 1.5 inch readout

- Conair lists a ten year limited warranty against defects in workmanship or materials
A fit for anyone who wants a plain weight only scale with a large readout and a long warranty, with no app or body analysis. Conair backs it with a ten year limited warranty, but there are no independent accuracy tests for this model to lean on, so the case rests on maker specs.
