Summary: Of you know a 10-key by touch and can enter quicker than most machines, this one is for you! I use to have to slow down because I would error out other (cheaper) machines, this one... Yep now the fingers can fly across the keys and it can keep up with me!
Excerpt: I used a Casio printing calculator for over ten years. this is a replacement. I wanted an exact model because of the placement of the keys. This is as close as I could find. It is longer than I was used to. Just have to adjust.I only used it for week. I will get used to it and it will be fine
