Texas Instruments TI83 Graphing Calculator

I have used the Texas Instruments TI-83 Plus edition all throughout middle school, high school, college, and now my guardian child uses it for her middle school work! The best investment I ever made for myself and my children! Very sturdy and the battery lasts forever in it. I think I have changed them maybe one time in all these years. A++++++

I'm very satisfied this item. The seller shipped it very fast. Item is like new.

This was the item I ordered, but was not the item I received from the seller. I went out a bought a new one while waiting on this seller to get in touch with me regarding a refund, which he never did. Amazon.com finally refunded my money themselves. This item, once I purchased it new, was very useful.

made several bids on ebay and was unable to win ,then this add for to buy
now came there it was for the same price for a used one that i was biddig on . my daughter was greatful to receive it so quickly

I received the above item with a battery that was corroded. I installed a new, uncorroded battery into the graphing calculator but the calculator did not work. I contacted the company and they reported that in 2 years they have never had a complaint. They did instruct me to mail it back with a copy of the e-mail regarding the problem with the calculator. We shall see how the replacement works.
