OSALO Extra Large LCD Display Big Buttons 12 Digits Desktop Solar Accounting Calculator (OS-2135 Pro)

• Irregular Highly Feedback Keys: Its keys are special and different from normal, making you have different touch feelings in different keys, helping you recognize what you pressed. Normal-use "+" and "=" are magnified, so easy to read them. Please kindly know that this is not a quality problem. If you mind this, we would suggest another style OS-6815. Welcome to check it in our shop
• Ergonomic Angle Display: When you put the calculator on the desktop, the 30° large display is just opposite your sight, more clear than a horizontal display. The big size and "click" sense of pressing the button make your every press more accurate, and work more efficiently
• Visualized Operation Symbol Display: When you would like to calculate the number, it will express the symbol (plus, subtract, multiply, or divide) on the screen. It can help you see the operation step when you operate continuously
• ABS Engineering Plastic: The Osalo 2135 Pro calculator is made of ABS high-strength engineering plastics, lightweight but durable. It can withstand the impact of falling on the height of the desktop 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 batteries （including one AAA battery） with double safe uninterruptible power. The calculator will shut down automatically after 8 minutes without operation
