What customers say about "Size & Weight"

Casio FX-CG50 Graphic Calculator

Lots of functions. Large keypad. Very good. Recommended.
Easy to use, light weight, ideal size :) its currently helping my sister through maths at uni so it was definitely worth it!
Great functions and very lightweight calculator, very comfortable to use.
I bought it last year and it works well so far, love the size and functions are great!
The calculator is quite bulky and not very portable when compared to other non-graphing calculators however the size is understandable due to the large amount of features.

Casio FX-CG20 Advanced Graphic Calculator

The right size and easy to use. This is absolutely what i needed and for the price it is affordable.
It is a little big in size but does an awesome job and more. Very satisfied so recommend it.
Calculator works great, plus it's easy to use. Light-weight in size, it's a great companion for any high-schooler to use!
It resembles a phone, therefore it does not cause inconvenience when you take it with you.
Weight may not suit everyone, it is heavy enough that may cause discomfort during transportation.

What customers say about "Display"

Casio FX-CG50 Graphic Calculator

Together with its large colour display, the result is aesthetically pleasing - more so than some of the T.I.s!
The CG50 has a clearer brighter screen than its predecessor, and it is also a litte speedier in its calcuations.
Screen is excellent and it's faster than the previous model with better buttons.
This is a great calculator to have with many functions. It is extremely helpful and has a great display.
Color display with many useful functions. Must have. Good value.

Casio FX-CG20 Advanced Graphic Calculator

Thanks to its unique digital colour display and powerful processor it can calculate even the most hardest of graphs.
Easy to use with common functions accessible in few keystrokes. Straightforward to program. Good screen - easy to read.
Great calculator makes maths much easier when doing graphs thanks to the color screen very easy to use.
As per Casio calculators it is really easy to use . The colour graphics are excellent.
After a year of use, I began to notice flickering on the screen. I was very unsatisfied because it was difficult to work with it.

What customers say about "Features"

Casio FX-CG50 Graphic Calculator

The battery lasts a long time, I have had mine for about 4 months and the battery is still pretty much full.
This feels well built and strong, easy set up, great functions.
It does everything I need, no issues, very quick on/off, seemingly low battery consumption.
The model was presented in 2017, so Casio should think about normal Li-ion battery, that you can charge through USB port and not think about stupid replacements.
Somewhat difficult to use, have to use non rechargeable batteries - likely to go through a lot.

Casio FX-CG20 Advanced Graphic Calculator

Simple connection to computer for backups and for showing output on large screen where it can be saved or printed.
Very impressive gadget I am doing a Psychology degree and bought it for the function of statistics I haven't tried it out yet but it is perfect for what I need to it for.
I found it quite easy to get it up and running with it's easy to use UI. Far too advanced for A Level Maths but becomes a very reliable tool for correcting stupid errors.
This is an amazing device, I connect it to my computer without any problems.
I was upset that after a while I began to notice that the battery was not durable. I had to change the batteries often.
