TI 84 PLUS CE Graph Space Grey

注文して届くまでに結構時間がかかり、その間の知らせもなかなか入らないので、到着するまで心配した。物は学校で使用するのでちゃんと動いてくれて良かった。値段が高いので買うのに迷うが長く使えるなら良い。

I bought this TI-84 Plus CE Color Graphing Calculator for my high schooler to use in class and for the ACT exam. This is actually my second purchase because the first one disappeared, and I needed a replacement quickly. I picked the mint color because it was the cheapest option at the time and had the fastest delivery. It’s used regularly in class and does exactly what the math teachers expect, with graphing, functions, stats, and all the typical coursework without drama. The color screen is also a nice upgrade because it makes graphs and menus easier to read compared to older models. The Highlights: 🔋Battery life is excellent: It charges quickly and then seems to run forever in normal school use. 🔌Charging port: this model uses a Mini-USB (USB Mini-B, the thicker style) cable (not Micro-USB). I can’t say what TI will use on future revisions, but this one is definitely Mini-USB. 🏫Test and school acceptance: the TI-84 Plus CE is approved for the ACT, and it also appears to be permitted under SAT/PSAT calculator guidance. We did not do SAT/PSAT, so we don't have firsthand experience. 👍Pros - Reliable for daily class use (matches what teachers expect). - Great battery life; easy to recharge (note the con below). - The color screen is easier to read than older models. - The slide cover protects well and stores on the back. - Approved for ACT. 👎Cons - Uses Mini-USB, not USB-C (one more older cable to keep track of). - Expensive to replace when one inevitably “disappears”. But you can lower the cost by selecting the right color. Overall, I’m very happy with the purchase. It’s been dependable for schoolwork, and I expect it will still be useful beyond high school.

I teach statistics, and use the TI calculators all the time. Mostly I use a TI-84. Unfortunately, it doesn't always show up on the overhead projector very well. For that reason, and to have a spare for students who forget theirs, I decided to buy the new back lit version. The difference on the overhead is amazing! This shows up great. Not only that, the graphs look much nicer than on the old one, and it has a few additional features that the old one doesn't. Considering that this was marked down due to package damage, I got a good price on it as well. I really didn't see that much damage to the package, but I sure did love the price! Only one caveat - the calculator doesn't seem as robust as the older models. It is nice and light though, so I suppose that's a trade-off. I didn't think the blue was quite as pretty in real life as it is in the picture, but I didn't buy it for looks, so that's fine with me.

it is spoilt and a used product. Can “turned on” but blank white screen. the packaging is missing and also no charging cable comes with it. Not sure how it passed QC check as it comes without an official package.

Why did you pick this product vs others?: I bought the TI-84 Plus CE in Radical Red for my high schooler, and it’s been a fantastic investment. It’s sleek, lightweight, and the color really stands out—definitely not your average dull calculator! The color screen is a big step up from older models, making graphs, equations, and data tables much easier to read. Color display – helps visualize graphs and functions better. Rechargeable battery – lasts a long time on a single charge. Approved for exams (SAT, AP, ACT) – works for standardized testing. Highly recommend for high school and college students. And let’s be honest, the Radical Red color makes math a little more fun.

So much better than the older models it more than justifies the extra cost.
