    Best Desktop Calculator

    • Good Quality
    • Easy to use
    • Batteries can be hard to find.
    I can't live without this calculator. I am ordering two more for my employees. They are using hand held Construction Masters now, but the desktop is a lot nicer at the computer. I have been using Construction Master & ScaleMaster for 20 years and live and die by them.
