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

## Features

- 【Irregular Highly Feedback Keys】Its keys are special and different from normal, make you have different touch feeling in different keys, help you recognize what you pressed. Normal-use "+" and "=" are magnified, so easy to read them. Please kindly know that this is not quality problem. If you mind this, we would suggest you another style OS-6815 of us. Welcome to check it in our shop.

- 【ABS Engineering Plastic】This calculator is made of ABS high strength engineering plastics, light weight but durable. It can withstand the impact of falling on the height of the desktop for several times.
- 【Dual Power】The calculator uses high conversion rate solar panels,solar power can be used in well-lit areas.At the same time, we provide matching battery（included one AAA battery）double safe uninterruptible power.The calculator will shut down automatically after 8 minutes without operation.
