In-dis-pen-sable!

I can now check the weight of my luggage before heading to the airport and to limit myself to just 23 kg (economy class) and avoid me unpleasant surprises for registration.

It's accurate: it allowed me to check that scales to registration are not always properly calibrated, and not to the benefit of the traveler ... It may possibly be used as evidence ;-)

It is very light: one can take him in his remorseless suitcase.

Its price is reasonable, I recommend it without restriction.
