Texas Instruments TI-84 PLUS CE Graphing Calculator, Black (Frustration-Free Packaging) (84PLCE/PWB/2L1/A)

My 15 year old grandson loves this....

Perfect for my classes.

Weighs nothing practically & the design is so beautifull.

Best calculator by far

received very quickly when ordered and the price was really good.

Exactly what I ordered. It was used, so its signs of age are expected. Unexpectedly was both the surprisingly good condition it was in, (the amount of wear could have just as likely been light chafing caused by the package shifting often in transit) and the fact that its previous owner thought one of the most basic formula Ive ever seen was worthy of writing on the inside cover. It was just in pencil and after keeping it for a time out of amusement, it easily erased off.

Im sure this is a good calculator, I havent gotten too far into the functions (though there is a steep learning curve). There are a few other issues that make the product difficult to use. 1) Who thought that using light blue and green together on a black surface would be helpful? Its impossible for me to tell the difference between the two colors that represent 2nd and alpha modes. I had to use a flashlight to be able to see the colors clearly, something that you may not have access to in a classroom. Another color that contrasts better would have been good. I was able to go off of the location, blue in the upper left of a key, green in the upper right, to tell which key/mode I was looking for. Except, the off button/mode is swapped. Just really poorly thought out. 2) No backspace button is a crime. Sure, you can use the arrow keys to go back, then use the delete key to clear the character under the cursor. But a calculator that was a fraction of the price of this, actually has a backspace button. Overall, Im not really that impressed with this calculator. I got it for the extra memory, as it will handle larger tables than my cheaper one. But if you dont need to process large tables (40+ entries), stick with a less expensive model. This one is actually disappointing, especially considering the price. If you cant get the UI correct, what are you even doing?

This is how we received our product… there was hair stuck in the tape, package had been opened previously, package was damaged. This was not frustration free nor a new product.

Personally, I think this is a good calculator, I would make the keys easier to click however because it is pretty uncomfortable. Otherwise, this is definitely better than my old version TI-84 PLUS Silver Edition. I like the screen brightness quite a bit and it is visiable
