Amazing it's a Good product

First off, this calculator has way more features than I’ll ever use or need, or be able to truthfully review. Sadly, my days of studying have long since gone, and I’m not a scientist or mathematician. But if you’re going to get a calculator you might as well get one that does just about everything. Just in case…So far I’ve used it only for the basic calculate functions. If or when I do need to do something a little more complex then I’ll definitely need to revisit the 44 pages of instructions. And doing the basics it has worked perfectly. The fact it’s rechargeable, and also solar powered, is great - there’s no replacing batteries or finding that they’ve leaked and caused corrosion after being left unused for a while.I’ve found the notepad extremely useful. I thought it might be a little gimmicky, but it’s proved super useful for jotting down calculations and measurements whilst carrying out odd jobs. I will point out that the notepad doesn’t quite have the contrast shown in the pictures, and it needs good lighting to be easily readable. The notepad also provides a snap shut case to cover the buttons and calculator screen. A magnetic closure ensures it doesn’t accidentally open.A couple of slight criticisms are perhaps the feel of the buttons and the quality of the plastic. Both feel a little cheap and brittle. If this calculator was slung in a school bag and not treated with care I suspect it may not last too long. If it’s treated well I think it will serve for years.

The LCD screen is a very useful addition that lets you jot down notes and drawings as you go and is cleared quickly by pressing the button. Very thoughtfully, the included defeat switch for the LCD panel can prevent accidentally erasing its contents.At £32.99 the NEWYES 991EX compares well to other premium quality scientific calculators.

Very good. Great that it has a drawing pad next to it.

I know we all have calculators on our phones but this dedicated scientific calculator is designed for serious scientists, engineers and mathematicians. I would say it was good for A Level students and upwards - it is not a child’s calculator. That would not only be a waste, it might confuse them. It is a decent size and needs to be because it has all the serious buttons. They press down in a satisfying way. - it can be very frustrating to be doing a complicated calculation and have buttons that are too sensitive or not sensitive enough. The use of the cover as a digital pad is a potentially useful addition. My clever nephew has been trying it out for me and gives it the thumbs up.

Love this calculator; so smart and shiny on the inside. Admittedly I don’t remember what I used a scientific calculator for at school, but they are super handy, easy to use and turn on and off. The rechargeable function is great. I particularly love the writing pad on the side, great for my bookkeeping course learning.
