Robust and precise!

Product quality:
The perceived quality is right.
On the housing, there is no creaking or yielding points.
Only the battery cover mechanism operates cheaply made and has a higher clearance on.
The integrated "LED flashlight" is gimmick - my mobile LED lights brighter ...

Precision:
I have checked the luggage scale with dumbbell weights!
2.5kg displayed with 2,55Kg
5.0kg displayed with 5,05Kg
10Kg displayed with 10,55KG

Cross-checked I have the whole thing with my digital bathroom scales Soehnle (plan on tiles).
This has shown at 10KG exactly 10,6KG, so I have to go out of tolerances my dumbbell weights :)

Application:
The weights I measured in the vertical position as possible.
For very large suitcases you can put on two chairs in order to keep the trunk as possible perpendicular to and so to get accurate results.

Conclusion:
This thing does what it says and who has ever paid for excess baggage at the airport, is likely to find the price more than reasonable!
