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: Smooth and handy - Great calculator the key buttons are very smooth and is real light and is a 12 digit number and is very useful and handy so I would recommend it very good quality. ## Features - 【Ergonomic Angle Display&Large Button】When you put the calculator on the desktop, the 30°large display is just opposite your sight, more clear than a straight display. Large and separated keys, make your every press more accurate. - 【Accounting Series】Silver panel with orange,blue and gray color buttons,vibrant color matching.The functions on the panel meet the needs of your accounting work and daily used. - 【ABS Engineering Plastic】This calculator is made of ABS high strength engineering plastics, light weight but durable.
