Texas Instruments TI-84 Plus CE Graphing Calculator, Bionic Blue

Excellent instrument. Fully meets the requirement.

Another great product of the great Company

Good Product.

Great Calculator. Can be used on all college entrance tests like SAT ans ACT

You can even play pokemon Red on it. Deducted one star because you cannot play pokemon black and white on it.

Ordered this product, received the black color. Since I'm abroad I can't return the product. This product costs 2000 rupees more than what I received and they are struggling to refund the difference amount and are giving reasons. Customer call executives are horrible, when we call to discuss our problems, they sit and laugh at our situation. I regret ordering.

It doesn't work. It was for my son's school work

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.

As order same received

Short version: Faster processor with more memory than even the TI-84+ C and a nice backlit color screen. This is a nice calculator. I bought this for general use to replace an old TI-84+ Silver. It has the same key layout and software as the older calculator. I like the new design with square keys a lot more. The thinner, lighter build is also very nice with no compromise in plastic quality. The screen is fantastic. Color means that multiple graphs can be overlaid and still be easy to tell apart. The backlight makes the screen very easy to see unlike the old reflective screens that aren't good in all conditions. An interesting change between the TI-84+ C to this calculator is the significantly faster processor (about 3.5x faster) and more memory (about 4x more). It still has the same system software, so it's just a TI-84 but it has a lot more horsepower and working space. I cannot speak to battery life yet. I purchased it about a week before writing this and it still seems to show nearly 100%. I do have a TI-Nspire CX CAS which is also rechargeable. I can use it for about two weeks before needing a charge and the standby lifetime is months. The same likely applies to this device. Both devices use a common USB Mini-B port for power and data so getting plugged in is no problem. They also included a cable with the calculator so you don't need to find one if you don't already have a bazillion of them. The only complaint is that some of the applications don't make use of the entire higher resolution display. It completely mystifies me that the graphing utility wasn't rewritten to take advantage of the whole screen. Instead, TI has the system place a border around the graph. TI is pretty good about feature updates so it'll probably get fixed. Is it worth the money? Yes, very much so but maybe price track it on CamelCamelCamel to see if you can grab one for $120. I really hope they make a TI-89+ CE.

I made it through high school with just a basic calculator, but in college I am taking calculus and chemistry, so I’m doing lots of math. I noticed that most of my classmates had a graphing calculator already and one of them recommended this model because she loved hers. This calculator can do so much more than my old one but it does take getting used to. There are three different actions for most of the buttons and so many features I still don’t know how to use. The features I like the most is the ability to copy an answer or equation previously entered, create tables for an equation I enter, and of course graph equations. It can even find characteristics of graphs such as critical points, max, and min. This calculator really can do it all. The only things it can’t do that I’ve discovered so far is giving simplified equations with variables, but that would make tests and quizzes too easy haha. The calculator is quite expensive but will last pretty much forever. The display is nice and bright, but can be annoying to keep awake at times if you are working through an equation with it on and don’t touch it for a bit. The screen will dim and start to go to sleep to save battery. While this is a good feature to protect battery I find it a bit annoying having to keep the calculator on while working through a long problem. Overall it functions at a much higher level than my old calculator and will aid me in my classes.

good received as desired
