The original color, translucent blue, that I ordered arrived and was nothing like the color depicted in the online photo. It was more like a washed-out grey. I was provided a new order in a different color. However, when I gave out the calculators, many recipients returned them to me, stating this doesn't work. Sure enough, 30-40[%] of the calculators don't work. So I think this purchase was a big waste of time and money (yours and mine).
