Calculators came obviously used, some faded markings on the buttons, and used stickers. However, it works fine. Compared to the prices of new calculators, it was worth getting.

This graphing calculator does not have as many features as newer models. This is the same one my son's school uses so we wanted to have the same model. I have trouble figuring out all the features, but have found great online tutorials to help. It is great for algebra and trig.

Works great. Batteries included with it ended up dying within 5 months, so keep a spare pack on you in case of emergencies.

Alright I cannot state I loathe this number cruncher. I chose to go for an utilized one since I will utilize it for only a semester. I suspected that by getting an affirmed repair one I will get a decent item. The mini-computer touched base with number keys in the wrong spot ( the number 9 was on the number 8 spot and the other way around), the keys for different capacities where switch and on various requests. Like the reasonable key was on the spot for the raise to the power spot and so on. The packaging still had soil around a portion of the screw openings and the packaging look like was quite recently dragged in a rock floor. In the event that this is the manner by which amazon guarantees their utilization items I rather run with other utilized item that are less expensive.

The TI-83 plus calculator was purchased for my daughter for her college algebra class. The item met the expectations necessary for her to calculate various algebraic formulas. Excellent calculator.

Great graphing calculator. Fairly easy to use. Wish it came with written instructions but you get a CD-ROM instead, which is fine. Still 5/5! I got it to use on the ACT.

The calculator works just great! They gave me everything that I asked for. However, i wanted a cover slide. The lady told me she can give me one for free. I love it now!

The only concern was that the cashier first doubted the availability of my calculator, but I still received it with no stress or hassle. Therefore, there was satisfaction.

Used my first one from college in the 90's till I dropped it in 2015. Bought the exact same model to replace it. Nice calculator.

I am going into High school and had one of these last year, which the school lent to us (Now I have bought my own). You can do almost anything with them. They are great for Algebra and graphing equations. I really recommend it.

My unit was listed as used and having some wear and tear. Honestly, thats all fine with me, seeing as I've never even seen or used a new sparkly one of these. I needed a T-84 Plus calculator, but those are just too damn expensive. What the seller DIDN'T MENTION is that they included batteries. Awesome, I thought. Until I checked the battery compartment and it had some corrosion in there. Its nothing too bad, but when I went to replace the battery and put the new one in, it stopped working. I cleaned up the battery compartment, tried my best to scrape off whatever was there and clean up the spring part because that was corroded as well, and after about 5 minutes of just taking at it with a tissue and some hand-sanitizer (all i had on hand), it works without question. This is basically the same exact thing, minus the older firmware and a few other functions, but as a senior in high school taking Calculus, this'll do the job fine. My original Ti-84 Plus got stolen, which sucks but this works the exact same. Overall, I'd recommend it alot, if you're willing to just deal with it if you get a unit like mine. Functionally its perfect. I'm going to open it later and see if the board got any corrosion. If it does, I'll make an edit to this post and return it immediately, but if not, its an awesome value.
