The claim

It will "firm and flatten your stomach in just weeks" and "takes just three minutes a day." It comes with a nutrition plan and a workout DVD. Try it for 30 days for $14.95 plus $34.50 shipping and handling or buy it for $200.

The check

We reviewed the nutrition plan, measured energy expenditure and muscle activity as two women and two men used the device, and had nine women and four men do the DVD workout.

Bottom line

Three minutes a day? That won't cause much weight loss. The device engages core muscles but burns no more calories than brisk walking. The nutrition plan is strict, so most people could lose weight on that alone. Just three of our 13 panelists said they'd consider buying the device.
