Texas Instruments TI-84 Plus CE Blueberry Graphing Calculator

As a highschool student, this calculator is really helpful. It's thin and lightweight, which is perfect for me as my school does not have lockers. The colored graphics are really helpful too. It made it easier to read graphs with multiple lines. The buttons were placed like the older versions, so I got used to this calculator quite easily. The battery is amazing too, I charged it fully the night I got it and did not recharge for three whole months. It didn't even die before I finally charged it. (Don't worry, it does come with a charger! And a manual booklet too!)Oh, because the screen lights up, just be ready to have teachers coming up to you thinking that the calculator is a smartphone! That happened to multiple times...once a teacher screamed across the classroom, "(insert my name) put that phone away or else you'll have to get it back from the office!" To which I replied, "it's a calculator" while waving the bright screen in the air from my dark back corner.

I’ve had this calculator for over a year now and it is still in great condition. I’ve used it hundreds of times and haven’t had any issues with it, it’s a great product.

My hubs bought this for me, as I needed a graphing calculator for school... and BOY, OH BOY! This puppy does it all! It's thin and light weight compared to all of the other TI-calculators I've used/tested. It has the ability to perform advanced Trigonometry, Precalculus, Calculus I/II/III, and *some* Chemistry and Physics functions. The color/backlighting feature comes in handy when graphing -- you can color-code different functions and the calculator will color-coordinate lines to match what you're doing (easy differentiation!). Have I mentioned the battery?! This calculator holds its charge like a BEAST! It's crazy... I keep the backlighting set moderately high, the thing stays in my backpack, I use it a lot (I'm a Biochem/ChemE student) and honestly, it holds its charge for MONTHS at a time. I was skeptical about the purchase, I read reviews and was on the fence because of the price... But, man... Totally satisfied!

As a math teacher of 15+ years this is a great calculator and fairly easy to use. The color is especially nice as my students don't have to then figure out which curve goes to which equation - they are different colors on the graph and in the equation list. This is also one of the many allowed on the SAT and ACT.

I bought this color calculator for my son. Everyone has the black one and it is so hard to find it when he lost it once. This is why second time buying this and I am glad I bought a different color.

3 years and it is still working. Son loves it. Hope he uses it when he goes to college.

So glad I upgraded to this from the older style. It’s brighter and easier to read. The multicolor functions on the graphs makes it really easy to quickly view multiple functions at once and evaluate them.The battery life lasts much longer than I anticipated. The battery lasts about 3-4 weeks per charge with me using it a couple hours a day. Very impressed with that as I was worried about having to constantly charge it.

TI calculators has a reputation for high quality products and this is no difference. This is performing as expected and is an excellent tool for advance math.
