When this item arrived it looked like it had been used.  I was skeptical but didn't want to hassle with a return.  I liked the idea that the cash register worked as a calculator, giving my preschoolers an opportunity to interact with numbers and math in a real way during their play.  The digital display is so faint that sometimes you can't even see the numbers on the screen.  The credit card slide beeps when you run the card into it, but it is barely audible.  I was immensely disappointed in these things, but kept the cash register so the students could still open and close the door, pretend, and handle the play money.  Now after just a few months the "open" button is no longer working.  This item had awesome reviews and I haven't found any of the key features to be worthwhile.  This wasn't worth the money and I even got it on sale.  I shoul dhave sent it back!
