Very Quick
"Cons: I realize this is the basic layout for many different scientific calculators, but it's kind of annoying that the percent key is a secondary function, meaning you have to press the "2nd" button, and then the left parentheses key to enter a percent."
"I've always used this particular model in high school, so I was excited when I saw there were different colors you can get it in."
"It's not enough for me to have issues about it (and I'd seen another reviewer mention the same thing so wasn't surprised when I saw the same thing), but I don't like buying X in description & Y in image....."
"It is very easy to use and has many of the same functionalities a graphing calculator may have, such as trigonometric functions and various essential constants; all in a much slimmer, smaller, and significantly less expensive package."
"Without those first foundational blocks, you just cannot move on to the next big thing."
"The buttons aren't quite as reactive, or rather- don't have that satisfying click when you push the button to let you know it was fully pressed, such as you might get with a TI-84 or something like that, but this is also much cheaper, and also much less bulky."
"I thought it was a pretty pink color with a modern floral design (even though im not really a pink girl but i wanted a bright color for it to stand out from regular black or grey ones) I really liked the floral design but, alas, NO FLORAL DESIGN!!!"

Quick
"Having a 2 line display helps in those instances where you come up with some weird answer, and upon review, you can easily see which variables you entered and realize that you fat-fingered in the wrong numbers... The calculator has dedicated buttons for Pi, Square root, Cubing (and any other Exponent) and many other functions I'm not smart enough to use (yet)... Cons: I realize this is the basic layout for many different scientific calculators, but it's kind of annoying that the percent key is a secondary function, meaning you have to press the "2nd" button, and then the left parentheses key to enter a percent."
"I've always used this particular model in high school, so I was excited when I saw there were different colors you can get it in... One of my favorite things about this product is that the memory functions are so easy to store and that you can solve multiple operations in one go!... But it's annoying during tests when I'm pressed for time to have to miss a question because I forgot to add a bracket in my calculation."
"for my 10 year old who is far more concerned about that than whether this is the right calc for school or not... and the fact that it continues with the green theme by having the lettering on the buttons in green, big bonus for her... It's not enough for me to have issues about it (and I'd seen another reviewer mention the same thing so wasn't surprised when I saw the same thing), but I don't like buying X in description & Y in image....."
"e the TI-84 model) allowing the student to bypass many steps and even reach the solution to some problems without any work needing to be done. It is very easy to use and has many of the same functionalities a graphing calculator may have, such as trigonometric functions and various essential constants; all in a much slimmer, smaller, and significantly less expensive package... The only issue I ran into is, on occasion, a button would not fully compress and enter the number or sign requiring a second press from me (my TI-84 never had this issue)."
"This calculator has been with me through thick and thin, and it couldn't have come to me at a more crucial time in my life... Without those first foundational blocks, you just cannot move on to the next big thing... If you're a teacher, and see a kid who catches on quick but can't do the 'easy' stuff, call the parent and tell them to be a good parent."
"My only complaint is that sometimes the buttons can be a little difficult to press quickly..... The buttons aren't quite as reactive, or rather- don't have that satisfying click when you push the button to let you know it was fully pressed, such as you might get with a TI-84 or something like that, but this is also much cheaper, and also much less bulky. I think I may upgrade to something like a TI-84 in the future for more advanced classes, but at this point it serves it's purpose well."
"I thought it was a pretty pink color with a modern floral design (even though im not really a pink girl but i wanted a bright color for it to stand out from regular black or grey ones) I really liked the floral design but, alas, NO FLORAL DESIGN!!!... And according to the previous reviews i'm not the first person this has happened too so be aware!... NB: Since writing my first review i would like to add that i was contacted by the seller who assured me that they are going change the photo as they no longer make the floral pink design's."
Less Quick
"Having a 2 line display helps in those instances where you come up with some weird answer, and upon review, you can easily see which variables you entered and realize that you fat-fingered in the wrong numbers... The included plastic cover is sturdy, it's fairly useful for covering up the keys so that you don't accidentally press the on button when the calculator is sleeping in your backpack... The calculator has dedicated buttons for Pi, Square root, Cubing (and any other Exponent) and many other functions I'm not smart enough to use (yet)... Not sure how long it should last, but I've been using it almost every day for a month, and the battery is great so far. Cons: I realize this is the basic layout for many different scientific calculators, but it's kind of annoying that the percent key is a secondary function, meaning you have to press the "2nd" button, and then the left parentheses key to enter a percent... The only other thing that bugs me is there's no dedicated "Off" button, "Off" is another secondary function... you'll be able to figure out exactly how much of a markup they charge for that green one."
"I've always used this particular model in high school, so I was excited when I saw there were different colors you can get it in... One of my favorite things about this product is that the memory functions are so easy to store and that you can solve multiple operations in one go!... I know some of you probably will say: "duh, that's obvious". But it's annoying during tests when I'm pressed for time to have to miss a question because I forgot to add a bracket in my calculation... I got an F on my quiz because I forgot to bring this to school one day and had to borrow the teacher's old CASIO... This is so much easier - and fool-proof, I should say, than most other scientific calculators. I hope this review was helpful to you, and that you learn from my mistakes and use mental math and dimensional analysis once in a while to prevent the occurrence of any errors in your work."
"Calculators are highly efficient, and TI makes great quality instruments..... for my 10 year old who is far more concerned about that than whether this is the right calc for school or not... and the fact that it continues with the green theme by having the lettering on the buttons in green, big bonus for her. The only thing I don't like is that the calculator in the image is all green..... It's not enough for me to have issues about it (and I'd seen another reviewer mention the same thing so wasn't surprised when I saw the same thing), but I don't like buying X in description & Y in image....... When online purchasing, the buyer evaluates the written data & reviews, but they also just as much evaluate the imagery as part of their purchasing choices... I will say that aesthetically speaking, I DO prefer the look of the all green w/swirls around the screen to the green with white around the screen..."
"e the TI-84 model) allowing the student to bypass many steps and even reach the solution to some problems without any work needing to be done. It is very easy to use and has many of the same functionalities a graphing calculator may have, such as trigonometric functions and various essential constants; all in a much slimmer, smaller, and significantly less expensive package. The display is a bit compact if you plan on entering very long strings of an equation, however it is easily navigable to make up for this. The solar power works well under normal fluorescent lighting conditions, and the cover also slips on and off very easily. Beyond the academic setting this calculator could be very convenient for home finances or any of the many tasks of life that require a little bit of calculation. I personally found it much quicker and easier to use than any phone calculator app I had. The only issue I ran into is, on occasion, a button would not fully compress and enter the number or sign requiring a second press from me (my TI-84 never had this issue)."
"I've had this model for several months, and the model before it for over fifteen years. From general math functions such as trig and geometry to physics and chemistry, this calc beats out all others... This calculator has been with me through thick and thin, and it couldn't have come to me at a more crucial time in my life... Without those first foundational blocks, you just cannot move on to the next big thing. I got to sixth grade and my math teacher then let me use this calculator, and I'm not even joking.... Be a good student and make your life a million times easier by buying this calculator. If you're a teacher, and see a kid who catches on quick but can't do the 'easy' stuff, call the parent and tell them to be a good parent."
"I am happy with this calculator, i use it for a college level intro physics, and also a basic electrical engineering class. I needed something that could do engineering notation- which this can... My only complaint is that sometimes the buttons can be a little difficult to press quickly... i find myself having to push a button more than once when I am trying to enter in calculations quickly. The buttons aren't quite as reactive, or rather- don't have that satisfying click when you push the button to let you know it was fully pressed, such as you might get with a TI-84 or something like that, but this is also much cheaper, and also much less bulky. I think I may upgrade to something like a TI-84 in the future for more advanced classes, but at this point it serves it's purpose well. Also i love the solar power too- less concerned about the battery running out on me during a big exam."
"I thought it was a pretty pink color with a modern floral design (even though im not really a pink girl but i wanted a bright color for it to stand out from regular black or grey ones) I really liked the floral design but, alas, NO FLORAL DESIGN!!! it is plain pink with a white square around the screen instead... And according to the previous reviews i'm not the first person this has happened too so be aware! If the calculator looked the same as the photo then i might haven given it more stars. NB: Since writing my first review i would like to add that i was contacted by the seller who assured me that they are going change the photo as they no longer make the floral pink design's... I have been using the calculator at school over the past 2 weeks and i actually think it's a great calculator. It does lots of cool functions to make Algebra easier to manage and i have lots of jealous girls in my class that love pink color."
