Lightweight and compact, it weighs luggage was a great help in our travels by plane because we chose a company that tolerates only 10kg in hand luggage and made to pay dearly checked baggage. We had kept a margin of error of 300g and realized that the device is reliable. The grip is actually very practical and can be attached with a strap system any baggage. A never forget in the future because we always brings back memories of travel, it prevents unpleasant surprises.
