Summary: If you want to pass the class, don't buy it. The screen must be broken, everything very fuzy on it and the some of the buttons don't work so you cannot see what you have entered. Does not create graphs at all.
Summary: When I put in batteries initially it would not turn on. Then I pressed on button again and it worked. Bought for grandson. He used for 26 days and it won't turn on. Then it would. This would happen quite frequently so changed batteries and it did not make any difference. Amazon accepted return. Now waiting for credit to my account.
Summary: The listing for this sounded too good to be true... The packaging it came in was horrid, there were marks all over the cover of the calculator. Also, the person promised batteries to go along with the calculator but there was nothing!!!
Summary: Make sure you have a lot of time before you need this product. It took me several complaints to actually get the product shipped. This was a horrible experience, but after over 2 weeks of waiting it looks like the thing should be here tomorrow. I only hope quality of calculator is better than service. I'm not expecting a lot, but when you advertise a product as "like new condition" than it should be in at least good condition.
Summary: I brought this calculator for an Elementary Statistics Course I was taking. The calculator looked cool and no one had one like mine, but after about 2 months, it would just blink out whenever I was working on it. I changed the batteries, tried to reload the programs on it, called customer support for Texas Instruments, and even went as far as to get an electronics technician to look at it. Nothing helped.
Summary: I read the reviews and only saw one person who was truly unhappy with the product. I didn't listen when the review reported that they shipped a broken product, this was a serious mistake. I received a calculator that was about as useful as a $36.00 paper weight they will claim that you can simply send it back, but they fail to mention or consider the amount of time and money wasted on their garbage product.
