The product feels uncomfortable if you are a casio buff. But, the product is excellent, its just a matter of getting used to the keys and position of the various buttons. It does take some time getting used to but totally worth it. I have a two casios 991ms and fx72, but this is the best that I could get for the same price. Remember the function keys are silver and not easily discern able, so, you can use a nail polish or some kind of paint which goes into the grooves and the keys are highlighted. The cover is a little cumbersome to operate. But, it fits the bill for me an excellent product from TI and my first calculator was also a TI in the late 80s. Review: If you got the money don’t look elsewhere! - A beautiful calculator, smoothest experience compared to the ones I have used.(casio 991ES and the Fx 82ms) >>>The +plus es: It’s mainly targeted toward algebraic calculations. Calculations involving lots of 10powers(like eltronic charges) are easy with EE button. Log,ln, and custom multi tap one button and more importantly you can go to your operations history and find the value of any line at any moment, which is not possible with the casio. Greatly useful when you get an error, or you want to calculate with a new set of values. There’s also a ‘setop’ function that helps to do common operational patterns with the press of a button. For example if you’re working with problems that involve numerous area of circle calculations, you can simply save an operator as pi*r^2 into that button. It’ll operate on any value and give a result without having to type the whole line every time. Storing temp values to variables and using them are much easier with this. Built in convert to different measurement units sometimes come in real handy(it also has some built in popular universal constants too, like value of k etc. just in case) Most importantly display has more size and it becomes real easy when you’re doing lengthier step calculations. And yes turning off the calc doesn’t erase your history, that’s good if you take a break in between. >>>The -minus es: So far so good, but this has some limitations. Once you move out of the typicsl algebraic field things get a bit lengthier with this. For example general arithmetic problems could get more time consuming since the square and under-root are now clubbed into one button. You need to first place ‘2nd’ then the square root to do that operation. Matrix size is limited to 3X3 instead of Casio's 4X4. I shall update if I encounter further Conclusion: Overall I’m satisfied with the product. I’m a BTech graduate so a good calc was needed. i would pick this over 991EX or ES. My calculations time has greatly saved. The price could be a bit lowered I guess, but texas is a marked brand in this field so I’m not surprised to see what they’re asking for this product. Overall definitely recommended. ## Features - It can solve the calculations problems regarding engineering, science and mathematics - Easy-to-use mode menu ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004NBZB2Y | | Best Sellers Rank | #41,145 in Office Products ( See Top 100 in Office Products ) #64 in Scientific | | Box Contents | .
