I've had this calculator for 2 months and there are a lot of problems. Do not buy this calculator if you value speed, simplicity, and reliability. It will work for slow, high-school calculations but cannot handle college-level, calculation-intensive functions.
I've been using TI graphing calculators all my life, but recently purchased the color TI84 since I lost my old black and white TI84. This new calculator is pretty horrible and doesn't fit my needs at all because although they increased the resolution and have colors, the company did not change the processor (and therefore processor speed remains the same). Therefore simple calculations like 1+1 take significantly longer to appear on the screen because the processor is slower to refresh the higher resolution display.
In addition, programs (even the simplest ones) take about 3 seconds to load, let alone run (compared to ~.5 on a B&W TI83 or 84).
Parenthesis and equation conventions have changed. TI thought it would make lives simpler by "intuitively" doing parenthesis for you, but in doing so, just made the overall accountability of parenthesis-heavy calculations more confusing and unnecessarily annoying. For example, doing e^(xyz)*(123) on a regular B&W TI would automatically put the "123" as a multiplier of the exponent, which is conventional in the order of operations, but on the TI84C, you must manually specify which term is the exponent and which is the coefficient, which does nothing but make the calculation more confusing. On multiple occasions, I've entered an equation and have it output completely wrong answers even when the equation on the display is accurate.Read more ›
I didn't realize that it had no batteries, you must charge it to work. I like that it is a lighter calculator, and it keeps a charge well. I wonder if it would last 3 hours with a regents..... especially after it ages a year or so...
Batteries are not an option with this calculator, so if during a test it loses it's charge-- you are out of luck-
I also had to load on all the apps: The directions were wrong. The directions had older versions of windows. (xp and vista), none were for windows 7 or 8 so if you have a new computer the directions don't work at all. It took me a few hours to get the apps loaded on. I had to look up online and it was very confusing until I found directions from anther teacher on what to do... which perfectly set it up.
It did not come with the dummies book inside as stated (which I already have and like). I was hoping to get a second one to keep in my classroom.
I love the PINK color, but it is just the top and inset, the back is white, and can get dirty.
I like the screen with the colors and it works well with shading. The new screen makes it easy to distinguish different elements.
With the screen the numbers appear smaller so it is difficult to read the numbers, compared to the older version.
I really like the calculator but it was very difficult to set up, and did not come with all the advertised items, so I can't give it a higher rating. I use this daily, and my other calculator was the TI84+c without the screen. I like that the calculators work the same way (unlike the older black ones which certain transactions (ie. inequalities) are done differently).Read more ›
Sure, it's not in the sub-$20 range. But (and talk to your advisor) if you don't need RPN (required by some schools, BTW) or the bells and whistles of this one's big brother (the 89) you will be really happy with this machine. The color graphing AND ability to import programs and images really make this unit stand out, stand up, and scream. BTW - it comes with an installed battery pack and a recharger - YES, the charger is included - and the cords to go from usb to the calc (also used for charging), or a shorty from calc to calc.
The REALLY cool thing, tho... if your school's math or science department uses it, it will drop into the multiple charging dock they have. Just make sure you get a "custom" replacement slide on cover (it comes with one that matches the calc, but you can do better!) or faceplate (both available here) AND mark it... because you will find everyone uses these machines.
The price - well, this gives up how old I am, but I remember when something close to this was in the mid-4 digit range price-wise (that's 4 digits NOT counting cents!!) and didn't do as much. at a hundred bucks and change, It's not cheap - but my oh my, is it worth the money? Until you have one, you may balk... but after you get one, you will smile and say... yep. It's worth it.
You won't be sorry.

The calculator works fine, but it takes forever to charge. The instructions says it take at most 4 hours to charge. When I charge it for 4 hours it's only 1/3 way there.Published 1 month ago by Amazon Customer
