Customer Ratings & Reviews

This graphing calculator is fast and holds a charge for a very long time. Programing and graphing are also easy.

I needed it for class & Best Buy offered price match, so I was able to pick it up in store for a great deal. I like that it has a rechargeable battery and that it’s in color. So far has been working great for my needs.

This works as described and is exactly what we needed. We encountered many issues with calculators with batteries that were bad and not replaceable. Best Buy was the only retail store that had these calculators and it worked!

I needed this for school. It has helped me with Trig and Calculus. If you have to graph by hand, this confirms that it was calculated correctly. Take out the frustration of math and get this. It is a must-have for all students.

I have used several time on my math exams, has never given me problems.

it serves the purpose it was bought for and usually lasts a long time unless the kid does not take care of it or submerges them into water etc :)

Works great very helpful tool for my daughter. Def recommend

I was recommended to get the TI-81, which is discontinued. This has color and a rechargeable battery. Kind of expensive but worth it when you really read the manual to unlock the potential.

This works fast at graphing problems. Figuring slopes to sine and cosines is nothing for this. Easily programmable and you pre stage many custom equations. A must for any high school or college math or engineering student. So. Is at NC State in engineering and uses this all the time.

Best on the market. Decent size, great battery, color display. What else needed, NONE!!!. A must buy for the school.

If you are looking for a calculator then this is the one! It is very amazing! I love how it is electric and it is super easy to charge. It functions perfectly, and has great battery life.

I got this calculator for college math. My daughter is also taking it in high school.

Being an engineering student, it's a necessity for a great calculator. Great purchase and love that i dont have to replace batteries. I just charge my calculator up lol

My soon needed a graphing calculator that was also on the approved list for the SAT. This is the calculator that is also used by all the math teachers at his school. He loves it, and it works marvelously. Never had an issue!

Kids needed it for High School and College needs. Best BUY matched Amazon and using rewards made the deal sweet Plus gave more warranty then Amazon.

Decided to take a statistics class in college and needed a calculator like this. It's simple to use and the battery life is great. A few of my classmates have the older version (TI-83) and it seems that the TI-84 is a little more user-friendly

My daughter needed this for school and used it taking her SATs. She said it really helped and is easy to use. My only complaint was the price, but Best Buy had it the cheapest. It's a lot of money for a calculator.

Excellent calculator, or has pretty of functions, made high school math way easier. Pretty good battery life.

[Employee of bestbuy] I love this product. Have used this before and wanted to buy one. Using the Best Buy app makes everything easier.

Purchased this for my daughter to use in school. I’m happy that she will be able to use this in high school as well since it is a little expensive. Still works great after almost a year.
