Good design, protective cover/ writing board
Let me say there lots of scientific calculator out there and GCSE mathematics suitable. I chose this as my eyesight cannot cope tiny buttons or lettering. The keys and signage is right font size for my eyes.The calculator keys are tactile to use, the screen size good enough to see the formulations without squinting. There is a built in stylus for you to write down the any formulas that need to park onto a secondary big screen that acts as a cover when you close the calculator.The calculator is a good investment to use at school, college or work. The secondary screen acts as cover when not in use. The calculator is not heavy in the hand.

Excellent product
I work as a neonatal nurse on a busy unit. As many places can relate we are going digital. Rather than using scraps of paper for calculations I wanted something I could wipe and use again that was portable. Looking longterm, something that would be of benefit to our son who is currently 6 (he loves numbers).I have tried the rechargeable calculators but found the battery stopped working a few months after purchase, hence looked for a better quality calculator. Although I could have bought a basic calculator for less, I opted for one that had more functions for the previous reasons. This calculator is light and fits nicely in my scrub pocket on my uniform and has survived being cleaned on a daily basis at work.The writing pad is big enough to write all the information I need when calculating drug doses. Easy to use and quick to press a button to wipe the information off the writing pad.

Good calculator but not for students
It is a good calculator and covers most things needed for the A level and engineering. The scribble pad is great for doing calcs on the job. But having the scribble pad does mean it can’t be taken into exams.
