They say here if you want to pass then get this calculator. Let me inform you this company saved my life! As a Mechanical Engineering student working towards my masters, I cannot express how this calculator saved me. My advice for those who really want to get an A+; Study hard but have this calculator as a backup since it can save your life when you forget something. It is really easy to use if you have one or two hours to sit and just get familiar with it. Also, when you have any issue setting it up (although its easy enough for a kid to do it), The Tech support will guide you through all the steps to get you started. Keep in mind that they are very patient and care for their customers. This is something that you will not see in most customer service companies. They are THE BEST JUST LIKE Their PRODUCT 100% if not more.

Example: I contacted them at 2:00 am and they got back to me in less than 2 hours with a solution (the solution was based on my mistake that I did on my phone, but they were more than glad to help). Also, their calculator was checked by my instructor during my exam (since all calculator must be checked by TA or instructor based on university policies) and my teacher was shocked that I am willing to use this normal scientific calculator rather than using TI-84 or even TI-89. My instructor even took the battery out of the calculator to make sure that there are no papers hidden and played with it. NO ISSUE. All my files were there and I got 100 on that test. FORGET ABOUT THE MONEY AND BUY IT, YOU ARE PAYING MORE FOR SCHOOL, AND THIS CALCULATOR CAN GUARANTEE THAT YOU PASS ALL YOUR CLASSES. I give this product 10 stars out of 5; yes it is that good. I would give it more if I could. Try it and you will fall in love with it. Also, all the notation for engineering is there (at least 80% of them which is more than enough). I let a friend borrow it and I was sending her the answers with my phone. Guess what she did not know any of the material and two days later she invited me to dinner since she got the HIGHEST grade in class. As long as the person can type the answer fast for you, you will pass 100%. THIS PRODUCT IS AWESOME, GREAT JOB AND BEST CUSTOMER SERVICE. I just want to say Thank You for Saving My Life.

Top Sellers! The new model is great. I was one of the first to try out the newest upgraded version. I made my purchase 2 months ago but the sales team told me I could upgrade my model to the latest firmware if I sent it in. The new file navigation features was exactly what I needed as it attracts too much attention if you need to hit the scroll button repeatedly to navigate through a file. Thanks again for the fast and professional customer service!
Yes! This thing is a weapon. Works like a dream, the attention to detail is there. Very happy, thanks team
Brilliant. Slightly concerened at first when I was having an issue with the Internet messages but was all good when I realized it was a problem with the Wi-Fi. Also fantastic customer support which helped me figure out the issue Fast response time.
I got this originally for Chemistry to help me remember the periodic table. Worked well with the note storage. I like it. I thought I was going to have to type all the notes in but I was able to send them through the app so that was good. Just need to type the notes on my phone before transfering. Worth noting that the calculator only supports text files so if you wanna copy pdf or word you need to copy and paste the text out of them first.
The messaging is pretty good. A little slow typing on the number pad but I've gotten pretty fast with practice.
Haha I love this me and my mate use this to share our multiple choice in bio lol
Good quality. Well made. Only wish would be being able to three-way chat to two other calculators at the same time
This thing is truly awesome; from the memory storage to the messaging between calculators to messaging my brother at home aha. I honestly thought I wouldn't be using the chat feature because I didn't think I could type fast on the number bad but its no problem
I procrastinated a while before pulling the trigger on this one, but I'm 100% happy I did now. I still believe in studying but some teachers make BS tests that I'll never need to know in real life
And the normal calculator functions are fine. Does the job
Awesome. Zero complaints. Ad was accurate
I first got the Gen1 of this last year. That was pretty cool but it only had messaging between calculators back then. Gen 4 (I think?) has come so far since then. I love the note storage. Saves me from remembering all the stuff that I would forget 1 day after an exam anyway :)
Take care with what subjects you bring this into though. If you try taking this into an English exam that won't go down well
This is so bad for my future hahahaha. Works great
So good! Zero chance any one would ever suspect this calculator. Looks 100% like any an authentic scientific calculator. A++
