This scale is comfortable to hold, easy to use, VERY fast, and the backlighting is useful in low light conditions.
It consistently gives the same same reading, as long as you follow instructions (lift the luggage vertically and hold steady for a second).
Mine has an acceptable amount of error (around -1%) so give 0,5kg of margin just to be on the safe side.
Only lacks an audible alert that the reading was taken, but a bright red light lit's up when finished and the reading is held, so that's not realy an issue.
Being this fast, if you can lift the luggage, you can use this scale.
