big, easy-to-use keys hearken back to those giant learning calculators i used in elementary school, which gives a nice sense of nostalgia while using this product.
it does compensate for the lack of a keypad on my laptop and it does what it is supposed to do, so i'm happy with it if not my mathematical acumen.
but if you just need to do basic math functions most of the time then this is a solid choice.
this is not a usb hid-class device, so it requires a driver, which is only available for windows.
great for commercial, high use purposes.
manual is an afterthought written by either by an engineer or a lawyer.
