Customer Ratings & Reviews

Price was comparable to other retailers, but other stores that listed this item didn't have the item in stock. Appreciated that Best Buy had the item in stock and you have options as to how you can receive your purchase.

Great product and cuts back on time doing math. Will recommend

I got a better price than offered by the manufacturer Texas Instruments itself with price match guarantee. Employee was very attentive with service and product was perfect. Would recommend for high level math!

Awesome calculator - one expects no less from TI. What sets this one apart is the fact that it is pc-connectible. You can import, rather than laboriously copy, your calculations.

This calculator is a must-have for college mathematics courses. It has all the necessary functions. Other models do not have the functions to complete the calculations I have been assigned to solve in my classes.

Its does everything as promised. My daughter is in geek heaven.

Has a lot of power in a small package. Can do many things a computer can, but in a smaller package. The price is teep, especially considering the non-Titanium version is much less and does most of the same things.

Son need it for first year of college. The unit seems quite sturdy. The sliding cover fit very well so the unit is well protected. Will see how long the battery life will be.

Awesome calculator easy to use especially for a beginner

Use best buy cause it's easy, convenient & reasonable. You always carry the brands & models for the electronic equipment I desire & buying on line with easy efficient pick up will keep me coming back.

Have only used it once it works exactly as it should

Got this for her calculus class. Also accepted on AP test

I am reviewing after a year. It has so many function and still learning . Engineering major and every calculus student should buy this one with no doubt.

All the functions work well. Needed this calculator for school calculus and no problems with it. Best Buy had the best price at that time for this calculator.

Its a good calculater and the best that I ever used

My daughter is taking calculus 2 as a first year college student, she's a math major and this calculator will scale with her. Recommended by my brother, a math teacher

If your class allows the TI-89 calculators then this is your new best friend! It can do many calculus operations that make checking your answer so much easier!

The TI 89 is the best calculator out there for a scientist. After I lost mine, I used my old TI 83 for about a year and it drove me crazy. I am glad to have a replacement.

A graphing calculator is needed for any engineering student and this one fits the bill. The online add-ons and preloaded apps make it great for mechanical and electrical students.

This calculator is required for math class, BestBuy was cheapest and ready to pick up in an hour. other online giant need 3 days delivery.
