Love this calculator.

Summary: I got this calculator about 11 years ago now and it has only barely stopped working. It got me through Jr. High, high school, and most of college. It was always easier and more intuitive to use than the TI calculators everyone else had,and so I'm thrilled to have found it available on Amazon.
Summary: i am an amazon prime member for two years now and probably purchase 150 or so products from amazon each year. in all that time i only wrote two bad reviews: one was for a dinky $2 product that arrived cracked and the manufacturer replaced it immediately, no questions asked.
Summary: The Hp 30s is the best calculator out there for its price. It is also the most accurate with 24 digits of precision compared to just 12 or 13 on the rest. Most of the people out there who dislike this calculator are hp traditionalists, and think anything without RPN is horrid.
Summary: For the price ($17 in our university bookstore), this is a superb calculator that offers both a quadratic and a simultaneous equation solver. Since it is not RPN, the HP fanboys will hate it, but it does offer a lot of features in a small package and is a great competitor to the TI 30X series.
Summary: This cheap calculator is my beloved. All my classmates in high school had Casios, and I could never understand why! This calculator is so simple to use, has quite an array of useful and extra capabilities, and I never even needed to read the manual!
Summary: It's a decent calculator but I have two complaints. The 'answer' key it's not easily accesible, It's necessary to use the shift key to recall the last answer. In an algebraic calculator the answer key is very important but in the 30S it's necessary to use the shift every time!!!.
Summary: For the money, this calculator is far ahead of others in its class. It can store ten variables and a constant expression using some of these variables. It can also store an expression with up to 4 variables using the HP solve system, which calls for inputs and solves the expression.
Summary: I am an electronics student, and I have TI, Casio, and Sharp. The first thing I have to say is how "SORRY" the instruction sheets are. I am as I write these lines, still trying to figure out how to use the percentage keys.
