What customers say about "Features"
Casio FX-CG50-S-UH 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.
