Flying has become a nightmare lately, especially internationally. All carriers have various luggage size and weight restrictions, and as overweight surcharges have become another source of revenue for airlines many carriers have started enforcing them rigorously.
There's nothing worse than getting to the airport and being told that the suitcase it took you hours to squeeze shut is just two lbs too heavy, and you have the choice to either leave something behind or pay a surcharge.

Of course, you always have the option to use your bathroom scale to weigh your luggage; it's cumbersome, and unless you have one of those fancy scales with a remote screen, by the time the suitcase is on the scale you can't see the dial. Besides, you're still left with the problem of finding a scale at your destination to get ready for the flight back.

Enter the tiny, 5oz Taylor #8120 Digital Luggage Scale. It's basically a handle with a strap and a small LCD readout. Attach the strap to your suitcase handle, press the button and wait for the readout to display 00; then, pick up the handle and lift the suitcase with it, wait for the beep... and read the weight of the suitcase on the display (it can be configured to show lbs or kgs)
It's so small that you can very easily find space for it in the suitcase you just weighted, your carry-on bag, or even a pocket if necessary.

The scale is powered by a standard user-replaceable CR2032 button lithium battery that should last many years.

A very inexpensive price to pay for convenience and peace of mind. Highly recommended.
