Black Hard Slide Case-Covers (See Description for Details) for Older TI 84 Plus, TI 84 Plus C Silver Edition Color, TI 89 Titanium Graphing

This graphing case is very durable and perfectly fits with my T1-84 Silver Plus Edition. The ruler is nice, and the indentation next to the coordinate grid can even function as a temporary pencil holder. I love this case, even more than the original. This is a must have accessory for college and HS students. The graphs etched on to the case also look very cool and it gives the case more "mathematical charm". :)

Innovative product! I love the vibrant blue color. Great fit! The "Made in the USA" Quality is evident throughout! I have used the template and straight-edge as a trial, and I must say, I am impressed. It is very easy to use. I will show it off at my college and illicit reaction. I am sure that the response will be positive...and envious. I am very satisfied with this EZ Graphing Slide Case. Packaging was superb and shipment was fast through Amazon. I highly recommend this item for those taking classes requiring the precision, accuracy, and or neatness when graphing!

Though I feel like it’s a bit pricey for a piece of plastic, it does get the job done. It may be a bit bulky for those who don’t actually use the ruler (the thing that makes it bulky).

Fits my TI84 plus perfectly! Mine was lost so I bought this replacement to cover and Im pleased that it seems as sturdy as the original. Its a little strange if you care about symmetry because the edges on both sides are different but I'm excited to use the ruler edge in my stats class. Overall great item!

I absolutely love my new EZ Graphing slide case cover. The cover fits on my calculator perfectly and has a lot of cool features. The x/y coordinate on the center of the cover is especially awesome as it helps me both speed up and achieve a better layout for my graphing problems. The centimeter ruler on the side is also great for drawing a variety of geometric shapes. I love that I don't have to remember to bring an extra ruler in my backpack anymore. This cover rocks! Also, I love the look and color of the cover. I use my calculator every day and it is so much more cheerful to see and use my calculator with it's cute pink cover. Overall, very glad that I bought it.

Why get a regular case when you can get this one?! This is a great product! It fits my TI-89 perfectly! It seems a lot sturdier than my old case. The graphs on the inside and the straight edges are definitely a fantastic touch.

My son has been using this for 6 weeks and it has already broken the screen. I’m sure it got smooshed in the back back. The graph line cut outs are cool, but they push in rather easily and it broke the screen. Now I have to buy another super expensive calculator.

First off, I use the TI-84 Plus Silver Edition. My initial impressions of this cover is that its a neat and possibly useful accessory for my calculator. Its numerous equations for the different types of graphs is certainly useful if you need a quick reference. The cut out at the top for a quick and easy graph making looks pretty useful as well and the two types of rulers will certainly come in handy. My gripe about the cover is that it is very much a standalone cover when you are actually using the calculator, because the rulers will get in the way off holding the calculator. In addition, the rulers itself adds bulk to calculator itself making it somewhat harder to grasp or hold. However, I do recognize that it is really the only place to put a ruler on the body. The material used for the cover is not like the glossy slippery original ones either. It's more matte and rough. A huge thing about the back cover is that it does not include rubber feet and any grippy materials leaving the calculator to slide around. If one was the use the calculator without the cover attached, then it would be fine but I do. A minor thing is that I don't really like how apparent the logo sticks out on the back. The TI logo is pretty small unlike EZ graphing. Overall, I'm not sure if it will beat my trusty ruler but I'm willing to use it in its place. It is definitely a solid product and if you are in need of an all in one package, then this would not be a bad purchase.
