If you're going to go beyond the elementary level use of Excel you need a manual or need to put up with the Help function of MS Office. MS Office's Help support isn't bad but it's awkward to work with and sometimes incomplete.

Not only are they pretty, they are a big hit at Tupperware parties. I even use them to write up my Avon orders. There is a color to match every house dress my husband bought me, but I am giving this product only one star because it doesn't have an eraser. When I attempt a mathamatical problem without a man near by to help me, I always mess up and need an eraser. Not that my vote matters, but, I say recall the product. I will never waste my allowance on these pens again.
