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++
