This is to review the product, not your buying experience (or bad experience).

The HP-41CV is one of the best scientific calculators ever made, probably only surpassed by the HP-41CX. It has all the necessary features needed in school and in your professional life, and that is why these calculators are still being sought after.

This calculator thinks like a mathematician.  Using this is a real pleasure.  No more need to figure out calculator-speak; just input the formulas and it crunches the numbers like a champ.  Can't go wrong with this beauty.

Yes, you're going to eventually need a graphing calculator at some point in time, but compared to other scientific calculators, this calculator is virtually unparalleled. Everything's quite easy to find on this calculator, and it can even solve moderately complex equations for you. The numbers are displayed quite clearly in a large fashion, so you won't have to strain your eyes to read them. As an added bonus, this calculator's also extremely durable - mine got run over by a car once (don't ask how, I don't know), and it's still in perfect working condition. It's cheap and it's effective - if you're in need of a scientific calculator, pick this up quick!

First thing to know is it comes with it's own down load cable and software. So don't and rush out and wast your money and buy one. However that being said do buy the optional keyboard if you plan on doing any programing or editing (which you will)Keyboard link http://www.amazon.com/Texas-Instruments-Keyboard-Graphing-Calculators/dp/B00007K7JE/ref=pd_sim_e_6
One nice thing with the software package and keyboard you can take notes in a lecture class and download the notes to a word processor program to print them out (with a bit of skill you can even hook Dragon program up to it so you don't even need to type.) Just one of the many things this calculator can do. If you can call it a calculator. As far as math go's it will work basic math up to the levels of nuclear physics, the many fields of Engineering and mathematics. This calculator will just about do it all. How ever you will have to learn how to do a lot of it by your self as support as in a user manual from TI is lacking. They is a lot of support sites online, many pre written programs available that are good and do work nicely with good documentation. So not all hope is lost in that area. So don't let that scare you away from buying this calculator. It's a work horse just waiting to get out of the starting gate. I highly recommend it! I use it everyday at work and have written many custom programs that make work easier,and continue to find new ways to use it. I've had it for almost 8 years and just got around to writing this evaluation of it.(and no the first one did not come from amazon and I payed a lot more that what they are want here for one) What made me write this is my first one was dropped 3 floors by a jr. engineer. On to the factory floor, this one is a replacement unit. So yes I do highly recommend this calculator for someone just starting out or someone with advanced math skills.

Need a calculator with EASY SCIENTIFIC NOTATION capability?  The TI-30XS is the gold standard for scientific calculators for students for pros alike.  The reason this is superior is because, unlike other sci calculators, you enter your math problem pretty much as it is written or the way to need it written.  Also, the big screen gives you four lines of math, not just one or two.  Many online video tutorials by students and teachers make learning to use the TI-30XS easier than reading the user guide.  It's durable, too.  You can drop it all day and it keeps working.  Remembers your last answer, unless you clear it out.  Switch to engineering calculator with a simple setting change.

I have never had a scientific calculator before, but needed one for a math class I am taking.  At first, it was very frustrating...  then I read the instructions.  ... and now I LOVE MY CALCULATOR!  It's much thinner and lighter than I expected, which is a plus!  It has a cover so that it does not get damaged when I throw it in the bottom of my book bag (the cover slips off the front and onto the back when in use so that you don't lose it).  It has two power sources (battery and solar), so I don't have to worry about working in areas where there isn't much light.  Since this is my first scientific calculator, I have no comparison.  But I really like the ease of use and how you can enter problem exactly as they appear in the homework.  FIVE STARS PLUS!!!

I love this new calculator. It's VERY noticeably faster than the previous editions and the resolution and color really help with making graphing distinctions. It may seem nitpicking, but those features really help when checking answers during a test or doing homework that requires graphing small changes.

The calculator is sharp looking and much thinner than my previous TI-83 Plus. The battery life seems quite long, I've used it quite often and have barely put a dent in the charge. This calculator also has an app feature that you can use by going to the TI website. There is a program you can use through your computer in conjunction with the calculator to add or use more apps.

The only issue I have, which is a personal preference, is the weight of the calculator. I like a bit of heft because it feels more solid in the hand and easier to keep from dropping. The calculator is much lighter and thinner than before which is great for putting into a pencil bag or stuffed backpack. I'm a bit clumsier and the light calculator just slips out of my hands sometimes. For that reason, I'd recommend a silicon gel case to go with this.

I love my Texas Instruments TI-84 Plus hot pink edition calculator very much! The Calculator came in the mail very quickly, and it was very great for it to come so quickly! I needed the calculator for my Math 112(Introduction to Precalculus with Algebra) class, and luckily it did come in time before my first test. Do you know what I love most about it? If you learn how to do all the special little tricks, you do not even need to know the formulas for your math test! You can just plug that equation right into this fancy-schmancy little calculator and it will give you the very correct answer! Yay for keeping a 4.0 GPA! Well, unless your teacher is like mine was and you have to actually show all your work. But that is still a-okay, because you can make sure you have the correct answer before turning in that test of yours! yay! I love this calculator so much. it comes with a charger, which is great, because you will be using battery. I lost the charger in my mess of a bedroom, but ordering a new one was actually very easy and fairly cheap. you can also personalize some the colors and I just love it y'all!

Fastest portable CAS graphing calculator you can buy for $. It also has slightly bigger screen than other competing models. There is a learning curve but practice/repetition makes perfect. Great for engineering.

The Casio fx-9860Gll Calculator is in the space age. They supply on line catalogs, teaching materials and all we need. It is reaslly easy to learn using the step by step instructions. I provides advanced physics calculation capacity. It's great.

I have six of these Casio Fx-300MS Scientific Calculators in my classroom.  I have found that this calculator is easy for students to learn and use.  It can do fractions, exponents and square root functions, among other things.  It is NOT a graphing calculator, but should be useful for a student working on algebra or pre-algebra.

This is the best and most portable calculator of its kind! Even though it has been around for a while now they keep updating and adding to the invaluable information that it contains. I use it on my phone and on my Kindle Fire when I'm out and about. It is the best investment I've made in a while! I got it from Amazon.com on a recommendation by my nutritionist.

This is one of the best Calculators ever produced. The calculator is complex enough to do double integrals and graph them, but it has a simple display screen and is very easy to operate.

I bought the Casio fx-9860G Slim Graphing Calculator because of the combination of enhanced and easy to use functionality, with a superb display.  After previously using other powerful calculators with tiny font sizes and confusing/massive instructions at times, this is a major step up.  It has everything needed for most mathematics - calculus, equation solvers, stats, spreadsheets, graphing, programming, recursion etc. and once connected to the Casio Web page using the included Casio software link, other apps can be added - the geometry app is fun and useful.  For the cost, this clobbers the higher priced competition - I donated a calculator that cost twice as much to my employer's charity Christmas raffles.  I had given up on calculators in favor of laptop/PC based math codes, but now it is fun again to use a calculator for courses and to just sit back at work sometimes & crank the numbers while going through tech. publications.

This is the forth calculator like this I have bought.  One a different brand and the other 2 have been from Calculated Industries (Maker of the construction master pro) and this has been the best one so far.

I love it's ability to handle feet and inches, built in trig (pich/rise/run calculation) that way I don't have to remember the sign cosign and tangent and how to use them. Built in circular calculations, ability to convert between metric and imperial (feet and in).

There are several other functions that are cool, but I do not use, like the ability to figure stairs, figure a compound miter, ex.

If you are looking for a calculator for a job site, or as a draftsman in my opinion you can not go wrong with this one.
