Great solar battery life

I use this daily in my office under fluorescent lights and it never seems to run out of power. The screen is very clear and big enough to read from a distance.

Good value for money

Does exactly what it says. The dual power feature gives me peace of mind that I won't be stuck with a dead calculator during an exam or meeting.

Loud and clear voice

I was worried the voice might be too quiet, but it is perfectly audible even in a busy environment. Highly recommend for anyone who does a lot of data entry.

Sturdy build quality

This calculator feels solid. I dropped it once by accident and it still works perfectly. The buttons have a nice tactile feel without being too hard to press.

Best calculator for seniors

Bought this for my mother who has trouble seeing small buttons. The large keys and voice confirmation make it easy for her to manage her budget.

Perfect for my accounting class

The voice function is a game changer when I am entering long strings of numbers. It helps prevent errors significantly. The keys are large and easy to press.
