Three-in-one set of calculator, notebook, pen and one
This scientific calculator integrates three functions of ordinary calculation, notebook, and pen, which is convenient for us to calculate in the process of study and work.
When you are calculating, it will not be inconvenient to remember numbers because there is no draft paper. You can remember the information you want on the LCD screen at any time during the calculation.
One-click elimination and privacy protection
When the calculation is done at that time, you can press the one-key elimination function key, so that all the records you left will be eliminated, preventing some trade secrets in the process of your work from being seen by others
Exquisite and compact, easy to carry
It is about the same size as a mobile phone, and it can be put in a bag or schoolbag when you go out, which is very convenient
Button battery is easy to replace
The button battery is plugged and inserted without screws. When the battery is used up, it can be replaced at will, which is very convenient.

The calculator is a very decent calculator, not over complicated. I will say it’s kind of difficult to know how many numbers you added to the equation. Some calculators allow you to see the equation you type down, this calculator does not, so keep that in mind. The pen is thin and flat, and you can see your writing pretty well. It’s not super large and it’s only a little bit taller than an iphone, not by a lot though. The calculator is accurate. The material is very plastic so it gives it the durability it needs, just do not try to bend it or anything that could potentially break it.

Calculator works as intended! The reason why i perfer this one over other calculators is the ability to also have notes to my calc. This drop the need to carry a notebook with me as Im able to physically write in my notes.

The calculator is good overall. The writing is a really neat feature I like. Unfortanely, it can be hard at times to get the writing to erase and you have to press the button a few times or close the calculator cover a few times and then press the button to close it. The buttons can be a bit sticky and sometimes double insert a number but I've noticed almost every calc does that to some degree

Originally, my goal was to find a more advanced calculator to learn how to use one more frequently, especially with everything going digital these days. Stumbling upon this gem, however, proved that I certainly needed something more, and this is certainly more than I would've expected at such a great price.With various functions, a sleek design, and a spacious scratchpad, this product is the most powerful educational tool I own. This multi-purpose product comes in the size of an iPhone 12, which means no more equations filled out on more paper than you know how to deal with, no more having to purchase more pens, pencils, or refills for either or, and no more clutter from overloaded folders lying around.The only downsides to its design are the soft buttons, lack of back-lit screens on both the LCD calculator display and the scratchpad itself, and the time it might take for you to read through the manual for proper use and functioning of this product. Even so, the manual is extremely insightful and guides you through every step with clear and concise instructions and imagery.Overall, this product is perfect for anyone who is looking for an affordable, multi-purpose calculator, so if improving your grades while staying proficient and organized sounds like something you'd want to try, I would highly recommend it!

This handy little calculator supported my sanity and helped me get an A in my college statistics course. However, after less than a year of infrequent use in my home office, the notepad screen will not clear, even with a charged battery. It is a wonderful device that comes in handy when writing out calculations & notes, and I would give it 5 stars if it still worked properly.

Excellent purchase. I bought this calculator for my daughter's school and she was delighted because it works very well. It comes with a pencil to write on the right side. She is delighted. I recommend it 100%.🥰🥰

Hard to see the screen sometimes and buttons push easily/randomly. As for the writing stick and pad doesn’t work at all you can’t see anything you write
