Title: only one out there
Review: If you want a keyboard for your calculator, this is your only option. It has all the letters, but it lacks other buttons such as some for programming which gives the keyboard limited functionality.It also comes with some nice software that is like notepad for calculators so you can save and manage your files. It's pretty easy to set up, you just have to download a new operating system for your calculator.Overall good accessory for every calculator finatic, somewhat pricey, but again, its the only one
