## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Great for the money
  

*by R***T on Reviewed in the United States on 21 January 2024*

The buttons feel great. The writing is good. I needed to set it up in lineIO MODE, and normal #2 mode for my needs. I never did look at the manual, great product imo.

### ⭐⭐⭐ 







  
  
    Deceptive Ad
  

*by B***H on Reviewed in the United States on 28 August 2023*

The good:  This is a basic scientific calculator which can be useful to those who have need of such a device.  The functions and features are standard without surprises.  I like that I can fold the cover to close the calculator.  Some calculators have a cover that can be removed, which leaves them vulnerable to being mislaid.The bad:  The note-taking function does not match the images in their ads. In the ads, the green traces of writing are bright as compared to the darker background.  In reality, the contrast is much less, and the green traces are not nearly as clear.  Since the only reason I bought this calculator was for the ability to take notes, this is a serious flaw and may result in my returning it.One star off for the deficiency in the hardware.  Another star off for lying to me.  Shame on you.

### ⭐⭐ 







  
  
    Not  a fan

This would be so much better if the side piece would play flat on the surface you have it sitting on
