What will you do if you find that out in the middle of an exam?
For important exam , purchace the genuine products and not unreliable counterfeits!

1Highly durable keys

GENUINE

Since these calculators are products used as educational tools for long periods of time, materials that ensure robust key durability and prevent wear or fading of key markings are used to ensure product quality.

2Drop-resistant body

GENUINE

High product quality prevents key malfunction or display (LCD) or key breakage when a calculator is dropped from a desk and hits the floor.

3Solar cell

GENUINE
Faulty wiring!

AN EXAMPLE OF A FAKE

Solar cells are indispensable for ensuring long-term use. With counterfeits, they may have faulty wiring, or may be there just for show to begin with.

4Battery

GENUINE
Almost impossible to
change batteries!

AN EXAMPLE OF A FAKE

Counterfeits consume 5 to 10 times more electricity! They may also have battery installed different than the designated one, rendering your spares unusable. The genuine products will last longer in operation and are consequently much more economical than counterfeits.

5Display

GENUINE
No metal panel
to protect the liquid panel!

AN EXAMPLE OF A FAKE

Genuine products have aluminium panel on the back side of the display for reinforcement.
With counterfeits, the display panel may be unprotected and more likely to be damaged.
