I've finally been able to get my hands on Zero's latest ZGC4 unit and so far and I'd like to share a review with Cemetech and discuss on it!



To start off, the calculator does feel nice to hold. It's not heavy or super bulky, and it's designed in a way where you can quickly jump in to solve those math equations you can't do in your head. The silicone lining around the shell is a nice touch to be more durable during middle and high school so it lasts longer. With it being lighter it won't hit the ground as hard if you were to drop it from your desk or a table if you're doing some homework during lunch. The buttons don't feel as tactile as the TI-84 Plus CE, but at the same time it does make it sound a little bit quieter to push. This may be a positive if you were doing hard-coding around other people so it might annoy them a little bit less.

Off to the software side, the operating system feels similar but different to TI-OS. Entries on the home screen are more organized with the separation of horizontal lines between each one so it feels easier on the eyes to tell apart. The menus feel pretty much the same as TI-OS so it's easy to pick up and understand. Several commands feel "right at home" coming from a TI-84 Plus CE user so you can easily pick up ZeroBasic quicker if you have knowledge of TI-Basic.

Now... all good things must come to an end and now I want to express my gripes on this calculator so far.

With the calculator being at a lower price point at $114.99 ($89.99 discounted on website for ordering), cheaper doesn't always mean better.



The calculator has a softer plastic compared to it's competitor and I have concerns about it's longevity. In the image above, the shell "bends" or "warps" slightly. Another thing I wanted to point out that some of the buttons appear to have a layer of paint over them (such as the 2nd key) and with that in mind I feel like it might show wear quicker. The finish on the calculator scratches easily, I can simply use my fingernail to permanently scratch it. If you want this calculator to look nice for a long time, I would avoid putting it in places where it can easily be scratched.



I also have noticed that the paint on the buttons can easily be scratched off with little effort by my nails.



The blue protective bumper on the calculator does not appear to be glued on and is showing it might not stick on the calculator for a while:



On the software side, there are basic features that are missing that you would have expected for them to be present on the calculator. For example, there is no built-in Python editor which is disappointing. As someone who didn't have access to their own computer throughout middle school, I would be sad if I had a calculator that had the ability to run python but not have a way to make anything on the calculator itself.

Comparing to TI-basic, there are multiple commands that are not present such as
Code:
Lbl
and
Code:
Goto
which hurt the programming experience a little bit if you came from Texas Instruments. I've noticed some bugs in the OS that aren't a huge deal, but bugs like "why wasn't this fixed before releasing the calculator?"

Before ending this review, I just want to point out that I understand the fact that Zero is a relatively new company and just jumping into the graphing calculator market and I do see potential with it. I firmly believe in the future it will be a good contender to Texas Instruments, Casio, Numworks, etc. in the future with further development. However at this time, I would not recommend a Zero calculator to your average student in Junior High, High School, or even college if you are seeking a calculator with graphing software to use for classes, as I would recommend a TI-84 Plus CE off of eBay if you were going to spend ~$90.

My final verdict of the ZGC4 calculator, it is decent for what it is. It gets the job done when it comes to math usage and basic programming, but right now it's not "ripe" for the market and it definitely needs time. It's a good thing to toy around with, but I would not say it is ready for commercial use with school districts especially since it is not ACT or SAT certified yet. Save a bit of money and buy a TI-84 Plus CE Python calculator when you can, it will save you the headache and you get FAR more support than you can with Zero right now.
I got mine last week, sort of similar feeling like why there is no python editor and buttons feel bit weird.

I did my normal testing that I do for all calculators that I have and noticed that python implementation is actually slower than basic, for example for loop from 0 to 10000 takes with python longer than same with basic, also saw some calculation bugs, like solver cannot find value somehow in some calculation where all my other calculators find.

Sort of mixed feelings with it, it is fast in some things and also python has extra libs where you could do nice looking gui things but why they have to copy most of UX from TI and why it is still feeling bit unfinished.

If a few things were polished out before the release it would have been a little better, but it feels too early right now. I'm not sure if the 4 is a prototype or not
I want to get one at some point. I really hate circular buttons on any calculators though. Compare the Casio fx-991CW vs the fx-991EX. It makes it feel cheaper imo.

Also, I can't pinpoint exactly why, (and it may be because of the circular buttons) but the buttons feel completely homogeneous to me. On other calculators, I like the way that the most commonly used buttons are usually larger (ex. the numpad). If you just change the color, it feels cheap.

But like you said, Zero is a new company and these are all improvements that could be made, and I think it will improve a lot in the future. Especially if it keeps up a competitive price point.
I have Casio fx-991CW and Casio Graph Math+ which both have circular buttons, they feel ok to me, but they have sort of round edges, so feeling is different to Zero's where buttons have hard edge and they are more up.

In picture below is Zero and that second mentioned casio.
