CATIGA CS-121 Scientific Calculator with Graphic Functions and Multiple Modes (Pink)

Great calculator at a good price for my son's Geometry class.

My son loves it! The calculater is great, my son is a junior in high school and isctaking college classes and this is perfect for him. It seems like its a little flimsy but as long as you take care of it it will last. It does come with batteries andca slide off cover. The instruction book is easy to read and pretty long but it does explain all the functions it can do. I really like tge color also and the display is really easy to read.

I usually use Ti calculators. This one is easier to use.

It takes some use to get used to it but it does all its basic functions plus more. Love the fact it can be turned off and on and that the batteries it requires aren’t your average. My hubby is newly taken classes online which this was much needed for.

this is the nicest calculator i have ever had. i took it to the grocery and knew exactly what i was spending and what a great thing to have at bill time . have been helping great grand child with her adding lesson. you can do so many things with the calculator my son is a engineer and he said it was a really nice one. I would suggest it is you are elderly and have problems at bill time it takes all of the worry off. i am enjoying my little helper so much

This calculator is just what you need for today's math. It's not simple at all but if you have complex math problems and/or equations this is for you. It comes with a cover/case to keep the buttons protected when not in use. It is a good size but not so big that it's awkward to handle. It will get the job done.

Used to solve complex problems in science and mathematics. Good resolution. Sleek design. Screen is a little light and could be darker. Lightweight, durable and good for engineering students also. Color is blue. A little difficult to get use to. A little bit of a learning curve to use it. Shows grafts and equations. Easy to carry in your briefcase since it is so light. It seems to programmable. Vital tool for many aspects of my business. Also handy in my stock market dealings. Figure out price of bonds and how long until maturity works good for me. Works well to keep up with my cash flow. Selling large pallets of product and shipping in my business it helps me keep on top of what is coming and going and profit margins. It has also all the features that a Normal calculator has plus more. This will take me a little while to get use to it and figure out how to use. This will come in handy for my business. Just wish the screen was a little more visible. It’s very light and difficult to read. So far this seems like a good product for my company but requires a good learning of all the features.

Good calculator that can show formulas. It features a large screen which displays graphs and equations, has multiple modes and ample functions (fractions, statistics, etc.). It has a cover that snaps/locks in place. It took a while to understand how it works (different functions than TI.). However, it is working for my son's school needs thus far. Cons: Uses 2 Button batteries (#CR2032)

nice big screen

This calculator is smallish (for a graphic calculator) and lightweight, which can be nice when you are already toting around a pack of heavy books, etc. It DOES work as an accurate graphing calculator, however, using it is less intuitive than a similar calculator at a higher price and quality level. Certain calculations require pressing more buttons to get the solution compared to say using a TI-84 to solve the same problem. I would recommend it only if you need something to get you by or for an issue where you need to save as much space/weight as possible.
