Scientists?
If you want a scientific calculator that does the job, bearing in mind, that, I have, as of yet not explored all of its' capabilities, this one will probably do! I am currently working on my pet subject, that being Trickynometry, and am pleased to report, that it does not calculate in blasted washing powder! I have given it a 4 star rating, as to achieve 5 stars, it would have to be, what is termed as a "model" calculator! I wish "A level examiners" were aware of this! They were, when I took mine! In conclusion, the calculator will do!

Plasticky and screen isn't as bright as on the advert.
It's very light, very plasticky. The screen is not as bright as shown on the pictures. It won't light up. You will be able to see the numbers of course but there's no difference on the colour of the background when it's on.

Said it is a graphing calculator but cannot figure out how to graph with it. Got many math teachers to try and no one can figure it out
