love the color

Nice Calculator!

UPDATE THE "e" function doesnt work little different from other scientific calculators but as long as you have the manual you will be fine, also sometimes when you push the numbers nothing happens and you have to push a second time, other than it's nice to be able to put the signs of operation in the order as if you were writing it just be sure to use the parenthesis or the solution will be different

As expected...nice for the price.

It is what you would expect it to be. Fast shipping.

This calculator is an upgrade. My previous calculator was 30 years old.

The overall quality is ok. Cover - The calculator cover doesn’t fit. It’s too big. It falls off which renders it useless. Can’t protect the calculator while in bag. Buttons - The buttons are loose and rattle which give it a cheap feel. Display - the display is ok. Directions - the directions towards how to use functions are quick, hasty, and require a lot of trial and error. Price - Great but it gets you marginal quality. Overall - it gets the job done.

It works my Stem In Algebra class in college.

The calculator works for what I need at a decent price. Its buttons are able to be read clearly etc and it gives the correct answers. Just two little things. 1) the actual calculator seems rather flimsy. Like if an average weight adult steps on it they will break the casing which is not brilliant but I use it at home at my desk so no big deal but still -1 star. 2) the supplied batteries came empty. I had to buy new batteries. That happens sometimes regardless of any products price point, so that didn't affect my rating. Was just a minor inconvenience.

Got this out of nostalgic curiosity for the days before use of calculators in schools shunted programmability to top end professional devices. AFAI can make out it is similar to the old Casio fx-6300g kit. Pleasant for taking me on a trip down memory lane but these days, if you want a programmable device, then I think you're better off getting a top-of-the-line model from one of Casio, HP, Sharp or TI. (I use an HP50g, which beats the pants off this Catiga offering.) It's minor saving grace is that it's probably the cheapest programmable you can buy.

Said it is a graphing calculator but cannot figure out how to graph with it. Got many math teachers to try and no one can figure it out

very handy exactly what my daughter needed

Ottima calcolatrice, funzionale e intuitiva
