Recently purchased my third TI-84 got my kids entering high school. After 7 years of use I can report durability, ease of use, and applicability from algebra 1 through calculous. This most recent purchase was for the plus with color and my algebra 2 student reports he likes the color graphing quite a bit. The first TI-84 is in its second year of college and going strong. It's probably a good idea to purchase one of the protective cases available on Amazon to protect this investment from the trials of the back pack.

AP/SAT/ACT approved graphing calculator. Both my daughters used this model throughout high school and into college. We bought a new one for my youngest to get the latest features but her five year old calculator is still going strong. Color graphing is worth the extra cost. The battery is replaceable and lasts 4-5 years and is not super expensive. Figure the cost per year and then invest in your child's education!

This is perfect for 100% of what you need to get you through middle school, high school and your college studies. Before you knock down the fact that I say "100% of what you need", understand that there are 2 other IT Graphing calculators that are more capable than this. However, those are NOT allowed on standardized tests. Compare to its predecessors this calculator is much faster and the colored screen "can be helpful" when you're plotting multiple graphs. Buy one in a color that you like, spend time with it, become friends with it and enjoy math. By the way, I read in some reviews that with this calculator you can't go back from decimal to fractions and/or vice versa. That's simply not true. Get to know the manual.

I bought this calculator for class. It works as described. I love the LCD lighted screen compared to the screen on the previous version without a backlight. The only thing I would change on a future version would be to backlight the buttons as well. I must say that we were required to download some programs onto the calculator for my class, but when I went to load them to this calculator they were already on it. I did have to load them onto a previous version of this calculator though. I feel like these calculators are worth the money if you need it for class and are required to have a TI 83 or 84. If you are just looking for a simple scientific calculator then you can easily find a cheaper one. This calculator is very durable and I believe it will last a long time as long as it is taken care of. I totally recommend this to anyone. The only thing I can think of that could be a con is the fact that the battery is rechargeable vs batteries you stick in the back. I believe this the case due to the slimmer build than the previous version that you pop batteries in. In any case, the battery does not run down quickly at all, just remember to charge up before class and you will be good.

Works very well and does math well. As soon as you pick up this product you will be at the head of your class so matter the subject. Math=Calculator, Science=Calculator, English=Calculator for heavens sakes even in gym if you whip this thing out and start mathing it up your peers and teachers will be so impressed that you will never get that super wedgie again along with a perfect A+ keeping your GPA at the best it can be.
