Ive been using this for a year.
-- extremely portable
-- love the fact that you don't have to strain and bend and twist to look at the reading, just lift the weight and keep it up for a few seconds till the light turns on and then let the bag go... the device keeps the weight displayed till then next reading.
-- it is so accurate that I take my bags upto 49.2-49.5 pounds and never once have exceeded the weight on the scales at the airports.
-- i have gifted this item to several friends who travel a lot.
