Guerrilla TINSPIRESTARHC Graphing Calculator, Starburst

First of all, it's a very durable case and nice looking. Many people have complained that it's almost impossible to get off or that it's too tight. We found it to be stiff and difficult to remove. It was a five minute fix that anyone can do. First of all, I'd like to say that you want the case to be tight. A case that pops off too easily isn't doing it's job, and the plastic will soften as it ages----so I'm glad it's tight. So----on the inside edge of the case, there are slight "widenings" of the plastic to "lock" it into position whether open or closed. Take a nail file to one of these and file off just a very little bit until it's easier to lock and unlock. It doesn't take much at all, and the case goes from being so tight it's unusable to being perfect. Good luck!

This makes my calculator look so much better, it is a little tight on it, but totally worth it. It is somewhat difficult to get off of the calculator the first few times you try, but through use and learning how to take it off better, it's become simple to take off.

When I purchased my inspire CX CAS online, it wasn't clear that it had a cover, so I bought this as well since the calculator will be riding around in my backpack. I gave it 5 stars because it cost less than a standard replacement, does it's job well, and looks fairly cool for Physics and Math classes. It seems to be fairly sturdy for what it is, and it's not going to fall of the caluclator.

The Guerrilla Hard Slide Case-Cover for TI Nspire is the perfect example of poor craftsmanship. 5 hours after receiving my package has left my brand new TI Nspire CX CAS with scratches on it. The protrusions designed to attach the case to the calculator are too large, which caused it to become stuck. The only way to get it off is to then use a small tool to wedge the protrusion from the groove of the calculator. It takes a fair bit of pressure to remove it.If you are capable of trimming down the protrusions, this product may work for you. You can do the manufacturer's job for them.Do not buy this product.P.S. I have provided two pictures. One with the case and the damaged done to my calculator, and another with the generic case as a comparison. You can clearly see that the Guerrilla case's protrusion is larger.

I love the case and it's great. It is glossy and looks good and is obviously good quality. The one problem I had is that one of rubber grips fell off. The only reason this happened is because it goes in my backpack and it gets crushed and it also get thrown around. That is my only problem. Otherwise great product for price!

Good quaility, great protection for my son's new calculator. Didn't want to spend all that $ on a calculator and then have it crash to the ground! This will help.

It's durable and adorable! I love it!EDIT (11/19/2015): This sucks so bad. This product just went from a wonderful five stars to THREE. There are two main reasons why.1) It is such a PAIN to take it on and off. Seriously, the case just fits way too tightly on the calculator. And from what I see, there are other people with this same issue. Just trying to take the case off the calculator, I tugged and tugged SO hard that my super, extra expensive calculator FLEW several feet away when I finally detached it. I've learnt from that experience, and now I have to detach the case so the calculator will fly into my lap instead of across the freaking room.2) Okay, this one is the one that upset me the most. If it was only for point number one, I would've left this review at five stars. But point number two definitely takes the cake. The paint peels off. I bought this case for the design. AND THE DESIGN IS COMING OFF. As of right now, the paint is only coming off at the sides. This is ridiculous because I haven't done crazy things with this case, and I've only had it for like, what, two weeks or so? Anyway, I've only had it for a short time and paint is already coming off. I know for sure that as more time passes by, more and more of the paint will peel. BOOOOO.

This was a gift for my granddaughter who wanted the Calculator for Christmas.Since this didn't seem like a fun gift for a 14 year old for Christmas I added this case to make it more fun.She loved loved loved it. She thought the special cover was the best thing. I heard to telling her friends and sending a photo to her friends.That made me feel really good and it was fun to surprise her.
