Review: Nice Desktop Calculator - Low cost but useable calculator. It has some useful functions like stringing multiple calculations together (i.e. AxB+C) and facilitating calculation of a long string of numbers that need to be added/subtracted, etc. large, easy to read digits. Large raised keys are easy to press and are far enough apart so it is unlikely I will inadvertently press two at a time. While it does have some photocells, I think you would need a bright area to actually get enough power to operate the calculator. I keep my office lights less bright so they don't interfere with my computer monitor. Fortunately the unit has a compartment for a single AA battery which powers the unit if the light is insufficient for the photo cells to provide enough power.
Review: ADD YOUR NUMBERS - Exactly as described: a good basic calculator, uses an easily replaceable battery, easy to see display, keys are of good size. Could do without the Grand Total appearing at times (can't be turned off). Good buy for the price.
