Great concept, works well
The dual power feature ensures it never dies during tax season. The writing surface is smooth and erases instantly. Only wish the writing area was slightly larger, but it fits most quick notes.

Student essential
As an engineering student, this saves so much space in my backpack. I can solve problems and draft diagrams right next to the calculation results. Highly recommend for campus life.

No more sticky notes!
I used to cover my desk in sticky notes for quick calculations. This device replaced all of them. The erase button is responsive and clears the board completely every time.

Perfect for my accounting desk
I love having the calculator and a quick note pad in one device. The LCD writing board is great for jotting down temporary figures without wasting paper. Very sturdy build quality.

Sleek and functional
The matte black finish looks professional on my office desk. Keys have a nice tactile feel, and the screen is bright and easy to read even in low light.

Good value for money
Does exactly what it says. The transition between calculating and writing is seamless. Battery life seems excellent so far thanks to the solar assist.
Q: Is the writing stylus attached to the unit?
A: Yes, there is a dedicated slot on the side of the calculator to store the included stylus pen securely when not in use.
Q: Does it have scientific functions like sin or cos?
A: This model focuses on financial and basic business calculations. It does not include advanced scientific trigonometric functions.
Q: Can the writing board save notes permanently?
A: No, the LCD writing board is designed for temporary drafts and quick notes. Once erased, the content cannot be recovered or saved digitally.
Q: How do I clear the writing board?
A: Simply press the dedicated 'Erase' button located near the top of the writing area to instantly clear the entire screen.
Q: What type of battery does it use if solar is not enough?
A: It typically uses one CR2032 coin cell battery as a backup power source when lighting conditions are insufficient for solar power.
