I had a second-hand one for my child that we like a lot. So when I needed to buy a pretend cash register for the Family Play Space at the library where I work, I chose the same one. I knew it was well-made, my child plays with it often, and I could remove the battery so it wouldn't make noise in the library. It still chimes when the drawer is opened, but no beeping with the press of every number. Even without the battery, the solar calculator still shows the numbers as they are added. I can't put out the coins for kids to play with, since they are a choking hazard, but the kids at the library love it anyway. It is played with almost constantly all the hours the library is open!
