pendancy Desktop Calculator, Extra Large LCD Display Computer Button 12 Digits Accounting Calculator (OS-2135 Pro-2Pcs)

Love the non slip and size. Makes one handed calculations easy.

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.

Great product. easy to read numbers, light touch key pads and everything it was advertised to be.

Nice desktop calculator. Keys work great smoothly with little sound. Also keypads fit tip of fingers well. Performs all functions for my needs. Battery or solar.

I bought this as a gift for my elderly father because it was a large size calculator with a bigger screen so he didn’t need to wear his glasses when he used it. It is dual power, battery and solar. It feels good to hold and easy to use. I’m going to purchase another for myself.
