Casio fx-570EX Clone

[AngsaEmas]

Hi!

I bought an fx-570EX clone a little while ago, can you guys see the difference?

Would love to see your opinions too!

Is there any of tests you would like me to do? Please do reply. Thank you

The things I noticed:

1. It is 2 to 3 times slower than the original, maybe I'll bring in an ES PLUS to test against it

2. The QR Code generated by the calculator for any calculations is fake, unscannable and is the same

3. The authenticity test doesn't generate any QR Code

4. The screen refreshes at a slower rate than the original

5. The answers calculated are sometimes differ by several digits
