The calculator is very durable. I know it is expensive but it is worth it. It is pretty large as well and is over 7 inches in length and over 4 inches wide. This is the second one I purchased from Amazon. I had to buy one for my other daughter when she took pre-algebra as well. The calculator comes with its own manual on how to use it.
Texas instruments is a good make and their products are known to last a long time. We expect our daughters to use these calculators through high school and college for math classes.
I am pleased with my purchase and recommend this product.
This calculator is missing some of the main functions I need for this class because it’s restricted and locked down. I’ll need to buy a cable and reinstall the Apps myself which is a further delay than I needed.
Buyer Beware, might be worth it to just buy it new. I feel like I got ripped off paying for this, even if it was only $70. Also an illegal product for me to own and for the seller to sell, these are for school use only. I’ll just have to make due until I finish the class and get rid of it.
I’ve attached photos where you can see where the paint job got messy and how some programs are removed. There is also the scraped section where the words “School Property” would be.
