Summary: This is my second Casio machine of this 12-digit, desktop style. The original one has been in service for a decade and is still performing great. This new one is for another location in our house and seems to be every bit as good as its predecessor. I'm delighted with them both.
Summary: I love having an adding machine and at least one other member of my team purchased the same one and she is equally as happy with her purchase. It is not overly noisy (but it's not silent) and it does what it supposed to do (math) I can't ask for more for the price.
Summary: very good for business calculations. only thing is confusing to calculate with proper decimal points; up above the f, cut, up 5/4. and the 6,4,3,2,1 0 x + add, that whole thing is a bit confusing otherwise very good.
