Stoney Meyerhoeffer: Product is great, but the workbook should be bundled with the 4065 calc rather than the 4080. I was disappointed to find a good portion of the workbook undoable because the 4080 replaces the Length, Width, and Height buttons with the Trig (sin, cos, tan) buttons. The bundle really needs to be changed. I had to order the 4065 and now have to return this 4080.

Ray P Hutchinson: Yes
I have been using the previous version of this for 30 years and after all that time the buttons finally did not work.
More than happy to have a new one

Anton: Great calculator for quick conversions and construction calcs to and from metric and imperial and mixing them up in between, which is pretty valuable. Buttons don't have that nice click to it that I'm used to from calculators such as the ti83, it's more stiff possibly to prevent button mashing and does slow you down a little bit. What I did wish it had was history entry display so I could enter a string of calculations and review or reuse them, my sharp calculator has this and it's a fraction of the cost.
