i posted the picture of the scale so you can see it. yes it works, and no, you can't see it when its on because really the only way to know it is on is when you turn it on through the program. and the green light on the scale will turn on. but i promise you it works, i just dont have a need for it anymore as the postal guy whom i always deal with is a sweetheart and changes packages they are in in order to make it cheapest.
