I hoped this would be a helpful tool.  It is less than useless.  I bought it before a trip, then my trip was postponed.  It was about a month later that I took it out f the package, and my first impression was that it is made of flimsy materials.  I removed the tab for the battery, and the display simply flickered.  Assuming I let it sit too long before trying it out, I replaced the battery.  Still no display.  I am out the cost of the scale, the cost of the new battery and I am lucky my bathroom scale is slightly within the ball park or I would be out the extra charges for overfilled luggage.  I would not recommend this scale.
