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. ### ⭐⭐ Poor Ergonomics *by C***N on Reviewed in the United States on April 16, 2022* The color on these is neat, but this seems like a downgrade from the original TI slide-case in almost every other respect.The case doesn't have rubber grip-feet on the back, so if you put the case on back of your calculator, the calculator will slide around on your desk during use.The act of putting on and taking off the case also has a noticeably worse feel than the original.Additionally, the rulers on the side and top of the case decrease the calculator's ergonomics very significantly, making it difficult/awkward/uncomfortable to pick up from most angles.Finally, I subjectively dislike the texture of this case compared to the TI original. It feels rather rough in comparison to the TI's typical smooth, glossy feel.I would highly recommend instead buying a TI-brand replacement slidecase directly from TI for a lower price. ### ⭐⭐⭐⭐ Great replacement if you have lost your original case! *by C***S on Reviewed in the United States on October 1, 2015* This is a sturdy case that fits my TI-84 Plus perfectly. The rulers/straight edges on the sides and top are very handy and the X-Y coordinate guide makes framing up your simple graphs a snap.My only qualms with the case are:1. There are no feet on the back to keep your calculator rooted to the table, a small bump can send your calculator to the hard floor if you have case on while the calculator is in use.2. The ruler edges do make the case slightly more bulky than it would be otherwise.3. The ruler costs nearly $20. Although it is a well engineered piece of plastic that fits my calculator well, it is still only a single piece of plastic. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/2775266-blue-hard-slide-case-cover-see-description-for-details-older](https://www.desertcart.vu/products/2775266-blue-hard-slide-case-cover-see-description-for-details-older) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
