Genuine vs. Fake: Comparison
There is a significant quality difference between CASIO original products and counterfeits, as shown below.
Especially in important tests, it is better to choose genuine products rather than take the risk of using unreliable counterfeits.

Fake Products
- Brittle and less durable

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